Christina Aguilera

In 1991, Aguilera auditioned for a position on The All-New Mickey Mouse Club (MMC), aired on the Disney Channel. She ran against 400 candidates, and while she made the shortlist she was ultimately rejected for not meeting the minimum age requirement.[28] One year later, in 1992, Aguilera received a call from one of the show's producers asking if she was still interested in becoming a "Mouseketeer". She once again competed for a spot (this time, against 15,000 candidates) and was selected to join the variety program the following year.[29] Her fellow cast members included Ryan Gosling, Keri Russell, Britney Spears, and Justin Timberlake.[30] During the show recordings—which included Aguilera performing musical numbers and comedy sketches—she moved with her family to Orlando, Florida.[31] In 1994, it was reported the series would not return for a new season.[32]

Aiming to beginning a music career, Aguilera moved to Japan in 1997. She was selected to record a duet with Japanese singer Keizo Nakanishi, with whom she performed in concert shows around the country.[33] Their song, "All I Wanna Do" was released as a single but failed to reach commercial success.[21] In June 1997, Aguilera went on to Romania to represent the United States in a singers contest during the Golden Stag Festival, but she failed to win over the audience.[34]

Seeking a recording contract, Aguilera recorded numerous demo tapes directed to record labels, including Walt Disney Records, for which she sent a cover of "Run to You" by Whitney Houston.[35] She eventually was chosen to record "Reflection", the theme song from the animated film Mulan (1998), which reached number 15 on the Billboard Adult Contemporary chart.[36] Following the attention she received with "Reflection", Aguilera caught the ear of Ron Fair, the A&R executive from RCA Records, who consequently signed Aguilera to the label.[11] In late 1998, she began to record her debut studio album into which producers reportedly invested over $1 million worth of writers, producers and vocal lessons.[11]

In May 1999, Aguilera released the lead single off her long-awaited debut album, "Genie in a Bottle", which topped the Billboard Hot 100 for five consecutive weeks and became the second best-selling single of 1999.[37] The song became an international hit, increasing Aguilera's popularity worldwide, topping the charts in over 20 countries.[38] The single also attracted the attention of conservatives including celebrities such as Debbie Gibson that spoke out against its lyrical content, and was eventually considered "too provocative" to be sung by a teen idol.[39][40] Due to the criticism, Radio Disney replaced the song with a censored version.[41] The song was nominated for a Grammy Award for Best Female Pop Vocal Performance.[42]

Aguilera's self-titled debut album, Christina Aguilera, was released on August 24, 1999 to critical praise and debuted at number one on the Billboard 200.[43] It catapulted Aguilera into fame globally and sold over ten million copies in its first year.[44] It was later certified eight times platinum by the Recording Industry Association of America (RIAA),[45] and has sold over 17 million copies worldwide.[46][47] Originally, Aguilera's desire was to create material directly inspired by R&B and soul, but the label opted for a more teen pop production due the genre's high financial return in the late 1990s.[48] At the 42nd Annual Grammy Awards, Aguilera won the Best New Artist category for which Time credited the award for "[helping] certify her credentials as a real singer".[49]

After the album's release, "What a Girl Wants", topped the Hot 100 and is recognised as the first new number one entry on the chart for the 2000's decade.[51] The song was also nominated for Best Female Pop Vocal Performance at the 43rd Annual Grammy Awards.[51] This was followed with "I Turn to You" which reached number three there,[43] and "Come On Over Baby (All I Want Is You)" which became Aguilera's third number one song and achieved worldwide success.[52] She also released a cover of "The Christmas Song" in November 1999 which peaked at number 18 and became the second highest charting position of the song after the original in 1944.[53]

With a new management, Aguilera started moving away from her teen pop niche and began working on a new project.[80] She cultivated a new image by adopting the alter ego Xtina, dyeing her hair black, and sporting several tattoos and body piercings.[81][82] Aguilera's new persona was widely criticized by media outlets.[83][84][85] In September 2002, she released the controversial song, "Dirrty", which garnered mixed reviews and peaked as number 48 on Billboard Hot 100.[48] The song's accompanying music video generated controversy for depicting overtly sexual fetishes,[86] and attracted the attention of conservative organizations and moralists who sought to have the video banned on MTV.[87] The video also sparked protests in Thailand and was eventually banned on the country's local television.[88][89] Despite the backlash, "Dirrty" topped the charts in the UK and Ireland.[90]

On September 22, 2023, Aguilera released "Learning to Fly" as apart of the soundtrack for PAW Patrol: The Mighty Movie.[322] The same month she performed at the EuroPride concert in Malta.[323][324] At the end of the month, it was reported that Aguilera would executive produce a stage adaptation of Burlesque.[325] In October, Aguilera announced that on December 30, she would begin headlining a second residency at The Venetian Resort's Voltaire in Las Vegas.[326]

Musicians such as Etta James (left) and Whitney Houston (right) was cited among Aguilera's main influences. She later recalled shaping her singing voice after them in her early years.[327]

Aguilera has named Etta James as a "role model", and said "At Last" made a major impression on her.[328] She later stated, "I'll still be as raunchy as I wanna be, and I'll have [Etta]'s memory to back me up. She's what I want to be someday".[329] As a young girl, The Sound of Music (1959) and its lead actress, Julie Andrews, became her early references to sing and perform, in addition to broadening her interest on Broadway.[330] Aguilera's other major influences include Whitney Houston, Mariah Carey, Billie Holiday, and Ella Fitzgerald.[331][332] She has also cited rock bands as an influence, specifically the Red Hot Chili Peppers, Nirvana, and Radiohead.[333][334]

Aguilera was also influenced by Latin music. She later recalled singing her first songs in Spanish during childhood, saying: "I grew up hearing [Spanish] being spoken in my household [and] hearing a lot of Julio Iglesias on the record player".[335] Some of her other inspirations in Latin music include Chavela Vargas, Vicente Fernández, and younger artists such Rosalía.[336][337] As a performer, Aguilera credits Madonna and Janet Jackson as major inspirations for being "positive female artists [who] aren't afraid to take chances, be daring, experimental and sexy".[338] Cher also encouraged her to being a performer and "a woman who has the guts to do [everything]".[339]

Aguilera's childhood visits to records stores moulded her taste and led to an appreciation for blues and soul music, which she called "music that really had heart".[340] Her music has also paid homage to many artists from this genre, including Aretha Franklin, Marvin Gaye, Nina Simone, and Otis Redding. Her album Back to Basics (2006) features inspirations of musicians from the early 20th century. As she later commented: "I was just so drawn to that [kind of music] ... [It] has so much pain, so much beauty of raw emotion and passion".[14] Her other influences in the genre was added for Liberation (2018), including Michael Jackson in "Maria" and Janis Joplin in "Sick of Sittin'".[341][252]

Outside of the music industry, Aguilera was inspired by actresses from the Old Hollywood.[342] She later stated, "I'm fascinated with the golden age of film. I wanted to capture the authenticity of the glam era", after which she cited examples such as Marlene Dietrich, Marilyn Monroe, Greta Garbo, Veronica Lake, and the pin-up models.[343] Her "Tilt Ya Head Back" music video also recreated Monroe's signature look, while the video for "Your Body" includes a directly reference to Lucille Ball.[344][345] The video for "Ain't No Other Man" presented Aguilera under the alter ego Baby Jane, which was inspired by Bette Davis's character in psychological horror film What Ever Happened to Baby Jane? (1962).[346] Her other inspirations mostly came from contemporary art, including works by Andy Warhol, Roy Lichtenstein and Banksy.[347][348]

Aguilera is known by her melismatic singing technique, yielding comparisons to Whitney Houston and Mariah Carey.[2][349]

Critics have described Aguilera as a soprano,[15][350] possessing a four-octave vocal range.[351] She is also able to perform the whistle register.[352] Maura Johnston, a journalist with Slate, called Aguilera's voice "an instrument that despite its ability to leap octaves has a low-end grounding similar to that possessed by opera singers".[353] The Boston Globe columnist Joan Anderman highlighted her vocal versatility: "[She] is a real singer ... blessed with the sort of breathtaking elasticity, golden tones, and sheer power that separate the divas from the dabblers".[354] In addition to sustain high notes, Aguilera is recognized for making use of the melismatic technique.[2] Jon Pareles from The New York Times emphasized that "she can aim a note as directly as a missile or turn its trajectory into an aerobatic spiral of leaping, quivering, and scalloping melismas".[252] Ron Fair—A&R executive from RCA Records—was impressed by her "perfect intonation", and concluded: "She's got the pipes to be the next Barbra Streisand or Céline Dion".[331]

Aguilera's singing technique also yielded comparisons to other singers. Journalist David Browne suggested that, alongside Mariah Carey and Whitney Houston, she "forms the team of the main proponents" of the melismatic technique.[349] Richard Harrington from The Washington Post also noticed similarities with both artists: "She has a genuinely powerful voice that's evoked comparisons [to them], though it for the most part avoids those singers' ornamental mannerisms".[355] The New Yorker columnist Sasha Frere-Jones also credited the technique by making her become "a serious singer without needing to reincarnate the Sarah Vaughan".[356] Songwriter Steve Kipner praises Aguilera's vocal dexterity, including her ability to "internalize[d] all the riffs from Chaka Khan".[331] Los Angeles Times music critic Ann Powers wrote that she possesses a "voice purely powerful as that of Etta James [...] and she's moving toward the expressiveness of Gladys Knight, if not Aretha Franklin". Powers also associated her vocal ability with Donna Summer when she performs records influenced by rhythm and blues.[357]

Aguilera, however, has also been criticized for the excessive use of melisma, as well for oversinging during her concerts shows.[358][130] The Huffington Post columnist John Eskow called her as "the main proponent of oversouling". Eskow recognizes Aguilera's voice as a "great instrument", although she "[doesn't] seem to know when to stop" with the use of "gratuitous and confected melisma".[359] Lucy Davies, music critic from BBC Music, raved about her "stunning voice", but offered that "she could be more varied, simply by cutting out some of the 'ye-e-eeeh, woah' in her songs".[360] Writing for Entertainment Weekly, Chris Willman credits Aguilera's tendency to oversinging as an influence of Mariah Carey, noting "her slightly nasal tone that really only becomes obvious when she's overselling a song".[361] Alexa Tietjen from VH1 acknowledged that Aguilera "does tend to take it to the extreme at times [...] but her vocal prowess is what's gotten her so far. Love them or hate them, the riffs are a part of who she is as performer".[362]

Aguilera's discography is generally categorized as pop, contemporary R&B, soul, and hip-hop.[364][365] According to critics, she has also experimented with other musical genres in her works. In a 2008 interview, she explained that she is "always inspired by new things" in music and enjoys "experimenting with [her] voice".[155] Alexis Petridis from The Guardian considered the "boldness in [continually] reinventing" her music as "one of her most impressive facets" as an artist.[366] Initially established as a bubblegum pop singer, she mixed teen pop and dance-pop on her first records, Christina Aguilera (1999) and Mi Reflejo (2000), with the latter also taking inspiration from numerous genres in Latin music.[355][367]

Moving away from the teen niche, Aguilera's post-2000 material mainly incorporated R&B and hip-hop.[364][80] Listed as an executive producer on Stripped (2002), she mixed both genres with Latin pop, rock, neo-soul, gospel, among others, while Back to Basics (2006) was described as a "throwback with elements of old-school genres combined with a modern-day twist [and] hard-hitting beats".[368][125] She continued merging R&B with other musical styles on Burlesque (2010), as well on Liberation (2018), which also features hip-hop, soul and blues elements.[369][370]

The show tune "Lady Marmalade" is noted as Aguilera's first musical transformation. Referred to as "too urban" by RCA Records executives, the song transitioned her music "from teen pop to a more mature sound".[118][371] Despite the renewal in her repertoire, Aguilera continued producing power ballads—which became a signature in her discography—in between her uptempo material.[372] Kelefa Sanneh, music critic from The New York Times, observed the continuous modification in her music, in addition to highlighting her "decision to snub some of the big-name producers on whom pop stars often rely".[373] Her notable sonically drastic ventures include the subversive futurepop on Bionic (2010),[374] electropop club on Lotus (2012),[375] and Mexican ranchera numbers on Aguilera (2022).[376]

Aguilera's music has been the subject of analysis. Critics have acknowledged domestic violence experienced during childhood as one of the main topics in her music.[378][379] Mary Anne Donovan, author of Christina Aguilera: A Biography (2010), noted that she "channeled her fear and sadness away from the abuse in her family to instead create the music that became her art and her livelihood".[380] It also influenced Aguilera's transition to adulthood and impacted many of her songs, whose lyrics reference female empowerment.[381][382] In a 2006 interview, she commented: "I feel a responsibility to share some of these things that aren’t kind of the brighter sides of my life. People [who] can relate might not feel as alone in the circumstance".[383]

Aguilera has also often defended the sex-positive movement and denounced social double standards in her music.[98] Reviewing Stripped (2002), Sophie Wilkinson from Vice opined that its music "explores nuanced articulations of sexual desires and fears while highlighting the social double standards", in addition to giving "any woman the confidence to take charge of her sexuality and ownership of her body".[384] Jennifer K. Armstrong, author of Sexy Feminism: A Girl's Guide to Love, Success, and Style (2013), opined that her music has "reject[ed] the double standards set forth by sexism and patriarchy".[385]

Chin Wai Wong from Hollins University also observed topics such as romance, introspection of vulnerability, gratitude for support, and sexual liberation in Aguilera's music, representing "multi-dimensional aspects of life [and] different social responsibilities a woman experiences".[377] While critics noted the feminist message in her works, Aguilera was acknowledged for her "refusal to sanitize her own sexuality to meet either the norms of mainstream gender politics or mainline Feminism's resistance".[386] The Guardian journalist Hermione Hoby opined that she "incites a sisterly spirit of collaboration [and] is not shy of the odd feministic declaration herself".[387] Other themes addressed in her lyrics include self-respect, body image, and LGBT rights, in addition to "fighting for creative freedom and gender equality".[388][389]

Aguilera's style and fashion has attracted significant media attention throughout her career,[405][406] and she has been named a fashion icon.[407][408] Jon Caramanica, journalist from The New York Times, concluded that "Aguilera will be remembered for her glamour and her scandalous take on femme-pop",[409] while Janelle Okwodu from Vogue noted that she "has never been afraid to take a fashion risk [and] has filled her videos with jaw-dropping styles and risqué runway looks".[410] Following her appearance at New York Fashion Week in 2018, Dazed named her one of the most stylish people of the year.[411] Aguilera's influence on fashion has been noted by several publications.[412][413][414][415] Samantha Sutton of InStyle noted Aguilera's influence on the rising fashion trends of 2021.[416] Writing for Vogue in 2022, Christian Allaire said that Aguilera was "ahead of her time" when it came to her 2002 image.[417]

Since the beginning of her career, Aguilera has attracted criticism for her revealing clothes,[418] and has been called a sex symbol.[356][9] In an interview with MTV News, Debbie Gibson accused her of "influencing girls out there wearing less and less", considering that "she lives and breathes the sexual image".[419] In response to negative comments, Aguilera stated: "Just because I have a certain image, everyone wants me to be this role model. But nobody is perfect, and nobody can live up to that".[420] VH1, included in the list of the sexiest entertainment artists in 2002 and 2013;[421][422] in publications from FHM and Complex, she received similar honors in 2004 and 2012, respectively.[423][424] In 2003, she was chosen as the sexiest woman of the year by Maxim, stamping the cover of the best-selling issue of the magazine's history,[425] and she was named one of the most beautiful people in the world in 2003 and 2007 by People.[426][427]

Aguilera was on the original panel of coaches from the reality competition show The Voice. More generally, she has been recognized for her contributions to American television and music competitions.[428] The New York Times, for example, noted that "She should also be remembered as the person who almost single-handedly reshaped music competition reality programming" while journalist Jon Caramanica pointed out that this was done at a time where numerous pop stars were becoming coaches and judges from American Idol and The X Factor.[429] As a coach on The Voice, Aguilera was listed among the highest-paid American television stars,[430] receiving $225,000 per episode in 2011,[431] $10 million per season in 2012,[432] $12 million in 2013,[433] $12.5 million in 2014,[434] and $17 million in 2016.[435]

Aguilera is noted for having reinvented her public image numerous times during her career.[436][437] Stereogum writer Tom Breihan noted that she "thought of herself primarily as a [...] young Mariah Carey-type",[438] but was instead marketed as a bubblegum pop teen idol due to the genre's popularity in the late 1990s,[439][440][15] following the success of Britney Spears's debut album.[11][441] David Browne of Entertainment Weekly noted that Aguilera was "a good girl pretending to be bad" when compared to Spears' music and image.[442] In contrast, Christopher J. Farley of Time considered her a more impressive artist than Spears.[49] Megan Turner from New York Post compared the "battle" between both artists in the media with the previous one between the Beatles and the Rolling Stones; however, she differentiated between Spears and Aguilera primary on the basis of image, suggesting that "while Britney has a va-va-voom sexuality [...] Aguilera had charm and a youthful appeal".[443]

Aguilera departed from the teen idol image with the release of Stripped in 2002, by dyeing her hair black, getting body piercings, and posing nude for several publications.[81] This was attributed to her provocative and extravagant alter ego named Xtina.[444] Serving as the host of the 2003 MTV Europe Music Awards, Aguilera opened the show dressed as a nun, accompanied by a choir singing the lead single from Stripped, "Dirrty", before showing off a more revealing outfit.[114] While analyzing her new visual, Vice and Rolling Stone magazines wrote that her new clothes echoed as if she were participating in the Girls Gone Wild franchise.[445][446] In a review of her persona, author Stephen Thomas Erlewine of AllMusic opined that Aguilera reached "maturity with transparent sexuality and pounding sounds of nightclubs".[447] Writing for The Daily Telegraph, Adam White was more positive about her image and recognized that her "embracing of an overtly sexual image in the wake of adolescent stardom was a tried and tested route to adult success".[448]

For the release of Back to Basics in 2006, Aguilera adopted a new persona named Baby Jane, named after Bette Davis's character in What Ever Happened to Baby Jane? (1962).[449] The image drew inspiration from actresses of the Golden Age of Hollywood, such as Marilyn Monroe, to go with the album's 1920s–1950s musical direction.[450] Starting in 2008, she adopted a futuristic image, which drew comparisons to the image of then-newcomer, Lady Gaga.[451][452] In 2012, she drew criticism over her weight gain from several publications;[453] the following year, she received favorable media attention after a significant weight loss.[454][455] In March 2018, Aguilera appeared on the cover of the spring 2018 issue of Paper, titled "Transformation".[456][457] Photographed by Zoey Grossman, the images featured Aguilera with minimal makeup and no photographic manipulation, debuting her freckles.[458][459] Her appearance in the pictures received significant media attention and widespread praise.[460][461][462][463] This led to other celebrities who had posed similarly receiving attention.[464][465] Starting in 2021, Aguilera began showing off a red-haired look for the promotion of her ninth studio album, Aguilera (2022).[466]

Various music journalists and authors have noted Aguilera's legacy in the entertainment industry[393][368][467] and deemed her as one of the greatest artists in pop music.[468][469] In 2004, she was listed as one of the most influential people in the music market according to The Independent,[470] and was ranked as the eight greatest woman in the phonographic industry by VH1.[471] Early in her career, Aguilera was labeled as a teen idol,[439][472] and has been named as one of the artists who revived teen pop in the late 1990s;[473][474] Time magazine stated that she was a "pioneer [in] a different type of teen stardom", crediting her vocal ability as responsible for the phenomenon.[49] Since then, she has been named as one of the greatest singers in contemporary pop music;[475][476] by MTV, she was ranked as one of the best voices in music since the 1980s,[477] while Rolling Stone and Consequence of Sound included her in their lists of greatest singers of all time.[478][479] In 2013, Latina honored her as the best vocalist of Latin origin in history.[480] With the recognition of her vocal ability and influence in the music industry, she has been referred in media with the titles of "Princess of Pop"[481][482] and "Voice of a Generation".[483][484][485]

Aguilera's star on the Hollywood Walk of Fame, received in 2010

Upon launching her music career in the late 1990s, Aguilera was named as one of the artists who shaped the "Latin explosion",[486][487] having contributed to the Latin pop boom in American music in early of the century.[488] Considered one of the greatest artists of the 2000s,[126][489] she has been classified between the main references of the Millennials;[490] writing for Vice magazine, Wanna Thompson analyzed her impact in the turn of the century, stating that alongside Britney Spears, "Aguilera dominated mainstream pop-related discussions. [Her] perfectly packaged music and looks appealed to tweens and teens who wanted to be like the pretty, chart-topping pop stars plastered everywhere".[491] The commercial success of her first projects as a bubblegum pop singer caused an effect that influenced record labels to invest in new artists who attracted the same youthful appeal, catapulting names like Jessica Simpson and Mandy Moore.[492][493]

Critics also highlighted the impact of her work in popular culture; while Stripped (2002) was called "the blueprint for divas making the transition from teen idol to adult pop star",[494] Aguilera is credited for "paving the way for a generation of pop singers".[485][495] Jeff Benjamin from Billboard stated that the album explored a "process of self-identification and declaration still influencing today's mainstream scene", in addition to "how of today's biggest pop stars have followed a similar path, exploring and incorporating these strategies into their careers".[368] In 2007, her self-titled debut album was added to the definitive list from Rock and Roll Hall of Fame, being recognized as one of the "history's most influential and popular albums".[496] Since then, Aguilera and her work have influenced various recording artists including Ariana Grande,[497] Ava Max,[498] Becky G,[499] Britney Spears,[500] Camila Cabello,[501] Charli XCX,[502] Demi Lovato,[503] Doja Cat,[504] Dua Lipa,[505] Grimes,[506] Halsey,[507] Hayley Williams,[508] Iggy Azalea,[509] Karol G,[510] Kelly Clarkson,[478] Lady Gaga,[511] Lauren Jauregui,[512][513] Meghan Trainor,[514] Miley Cyrus,[515] Nicki Nicole,[516] Olivia Rodrigo,[517] Rina Sawayama,[518] Rosalía,[519] Sabrina Carpenter,[520] Sam Smith,[521] Selena Gomez,[522] K. Michelle,[523] Tinashe,[524] and Troye Sivan,[525] and athletes such as figure skater Johnny Weir,[526] ice dancers Zachary Donohue and Madison Hubbell,[527] and swimmer Dana Vollmer.[528]

Aguilera has also been praised for emphasizing the importance of feminism in pop music;[388][529] several journalists agree that her use of sexual imagery has helped catalyze public discourse on the topic.[445][530] Lamar Dawson, columnist from The Huffington Post, praised her feminist efforts in the music industry and recognized that "while Christina isn't the first pop star to place feminist rhetoric into pop culture, she led the charge at the beginning of the 21st century of influencing the next generation of impressionable teens who were too young for Janet [Jackson] and Madonna's curriculum".[531] Gerrick D. Kennedy from Los Angeles Times shared the same point of view and stated that "for a generation who hit puberty during the great 2000 pop explosion, Aguilera was an essential voice with music that tackled self-empowerment, feminism, sex and domestic violence — subject matter her contemporaries were shying away from".[365] Rhiannon Lucy Cosslett, co-founder of The Vagenda, opined that the provocative dance routines in Aguilera's music videos were "empowering",[530] as she has been referred to as the forerunner of the slutdrop dance style.[532][533]

Aguilera's videography impact was also analysed by music critics. While "Dirrty" (2002) has been described as "one of the most controversial videos in pop music history",[534][467] and one of the greatest music videos of all time,[535] Issy Beech from i-D recognized that the audiovisual work "paved a path for videos like "Anaconda" and "Wrecking Ball" [...] paved the way for open sexuality from women in pop".[536] In the video for "Beautiful" (2002), the highlight scene of a gay kiss has been considered one of the most important moments for LGBT culture,[537][538] in addition to start Aguilera's image as a gay icon.[539] Both works was elected as one of the greatest music videos of the 21st century by editors from Billboard,[540] while she was named one of the greatest women of the video era according to VH1.[541] In 2012, her videographic collection and some looks used throughout her career were part of an exhibition by the National Museum of Women in the Arts aimed at illustrating "the essential roles women have played in moving rock and roll and American culture forward".[542][543]
