(Love is not as it looks) (2000, Azteca Uno, Mexico): Vanessa Acosta as Alicia "Licha" Ramírez Campos. El amor no es como lo pintan concluded in 2001.

(There's No One Like Jassi) (2003, SET, India): Mona Singh as Jasmeet Walia. The Indian version is not so much about beauty and ugliness, as about a simple middle-class girl with strong family values being catapulted into the amoral world of high fashion upper society, although Jassi was made to appear ugly by having on thick rimmed glasses, braces and an unsightly hairstyle. Jassi Jaissi Koi Nahin concluded in 2006.

Turkey's "Sensiz Olmuyor" (Won't Work Without You) told the story of Gönül and Arda on two separate TV networks, with each channel showing thirteen episodes. When the weekly series debuted on Show TV in January 2005, Özlem Conker played Gönül (which means 'heart' in Turkish), the intelligent swan in ugly duckling clothing, and pop star Emre Altuğ appeared as her boss and love interest, Arda. The show did not go on hiatus when it was moved from Show TV to rival network Kanal D, but there was one big change: Yeliz Şar took over the role of Gönül, but the rest of the original cast remained intact.

In February 2005, the German TV network, SAT 1, began airing a version called Verliebt in Berlin (The title is a word-play and can mean either In Love in Berlin or In Love with Berlin), starring local soap opera star Alexandra Neldel as Lisa Plenske and Swiss actor Mathis Künzler as David. The show had 5 million viewers daily and was extended beyond its initial 250-episode run in early 2006.

A few weeks later it was announced that the show would be renewed for a second season, but without Neldel and Künzler. The focus shifted onto a male lead character named Bruno Plenske (Lisa's half-brother, played by Tim Sander). Without Alexandra Neldel, however, the show lost much of its original appeal and dwindling ratings led to its cancellation in 2007. Verliebt in Berlin has also been broadcast in dubbed versions in Hungary (as Lisa csak egy van) and France (as Le destin de Lisa). Although Verliebt in Berlin continued with new featured characters and original storylines, it is still credited as "based on Yo Soy Betty La Fea".

(Be Not Born Beautiful, from the Russian phrase, "be not born beautiful, but be born happy", "Ne Rodis' Krasivoy, Rodis' Shchastlivoy")

Despite the original Colombian production already being in Spanish, Telecinco launched an adaptation in Spain called Yo soy Bea in July 2006. The Spanish version title (which translates to "I am Bea") is a pun, with "Bea" sounding like both fea ("ugly") and bella ("beautiful"), and being the short version of the protagonist name, Beatriz. Ruth Núñez played Beatriz Pérez Pinzón and Alejandro Tous was Álvaro Aguilar, the company boss.

It has become Spain's top-rated daytime programme. Ruth Núñez, known to Spanish viewers for her portrayal of a Yugoslav student in teen soap, Compañeros, plays the heroine.

In this version, Beatriz Pérez Pinzón (Núñez) is an unattractive 26-year-old economist whose looks aren't important to her. She's intelligent and kind, and one day, after having cared for her widower father for two years, she decides to look for a job. Although she's very well educated, she gets only a secretary job at the magazine "Bulevar 21". She becomes the secretary of Álvaro Aguilar (Alejandro Tous), the company boss. In the company, Bea will be against Cayetana (Mónica Estarreado), Álvaro's fiancée, and her friend Bárbara (Norma Ruiz), who is also Álvaro's secretary.

ABC would acquire the series under the title Ugly Betty, and initially slated the program for broadcasting in summer of 2006 as a daily series, but its success led to ABC slating it as a weekly series.[7] The hour-long program aired Fridays at 9:00 pm (Eastern time);[8] the first episode was broadcast 28 September 2006.

Mega Channel in Greece is airing its own version titled Maria, i Aschimi (Μαρία, Η Άσχημη – Maria, The Ugly One) starring Aggeliki Daliani and Anthimos Ananiadis . Maria exudes intelligence, humor, and kindness, but what she is missing is conventional beauty. She considers her appearance to be an obstacle in her search for employment, despite her collection of degrees, which are displayed proudly by her parents, Kaiti and Irakles. Having no luck in her job search, Maria decides to try for a job for which she is overqualified, secretary to Alexis Mantas, the director of a noted fashion house called Ecomoda. Alexis is the most coveted bachelor in Athens, but he has recently gotten engaged to Markella, who tries to get him to choose her best friend, Lilian, to be his secretary and to keep an eye on him. Lilian doesn't have Maria's natural intelligence or fine education, but she has a beautiful appearance, which makes her a better superficial fit at the fashion house.

This adaptation was originally supposed to start airing on 1 November 2006, but within two weeks of that date the show was removed from Mega Channel's schedule. Finally, it began on 1 January 2007 at 21:00 and although it was scheduled to move at 18:15 two weeks later, due to its high ratings (± 45% according to Agb Hellas and more than 2 million viewers) finally remained in the prime-time slot of the channel.

Georgia's version of the Betty story began on 24 May 2010, about one month after the U.S.A.'s Ugly Betty ended. The first episode was a pretty faithful remake of the pilot episode for Ugly Betty, with only minor changes, making this the first series to be adapted directly from the American Ugly Betty and not the Colombian Yo soy Betty, la fea. The series stars Tina Makharadze as Tamuna and takes place in Tbilisi, the Georgian capital (Tamuna lives in the outskirts, hence the show's title, which translates as "Girl from the Suburbs").
