Patito Feo (in English, Ugly Duckling) is an Argentine telenovela produced by Ideas del Sur that aired in first run on Canal 13 from 2007 to 2008.

Patito Feo is set in the Pretty Land School of Arts, a prestigious private music school on the outskirts of Buenos Aires, with a major plot line revolving around two teen girl groups – Las Populares, led by Patito Castro (Laura Esquivel) and Las Divinas, led by Antonella Lamas Bernardi (Brenda Asnicar) – who will compete to win the talent show and sign a record label.

Patricia, lovingly known as Patito, has to leave her humble life in Bariloche with her mother, Carmen, to move to the big city of Buenos Aires.

In Argentina, 400.000 tickets were sold for the first national live tour,[5] over 150.000 in Buenos Aires and 90.000 in the litoral city of Mar Del Plata during the summer.

Afterwards, the complete cast toured Latin America with over 700.000 tickets sold for shows in Mexico, Chile, Colombia, Peru, Venezuela, Panama, Dominican Republic, Uruguay, Guatemala, Costa Rica, Nicaragua, Ecuador, El Salvador, Bolivia and Paraguay.

Although the show was incredibly well received by the audience, Patito Feo attracted huge criticism due to the fact it glamorized the villains, a group of mean and beautiful girls that called themselves Las Divinas (The Divines).

The fact the villains were much more popular among young girls than the main character caused concern over some groups and the issue was even on the cover Noticias, Argentina's most important current affairs magazine, under the headline "The Triumph of Discrimination".

Due to the big popularity, a huge merchandising line was unveiled and Laura Natalia Esquivel visited the country to promote the show.

However, a new musical with local actors was licensed and, even though none of the original cast members were part of the production (with the exception of Laura Esquivel for a few special presentations), over 250.000 tickets were sold in Italy and Spain.

At the same time, Ideas del Sur started to develop a new youth-oriented show, Malcriados (now titled Consentidos), and chose Brenda Asnicar, who had enjoyed high popularity in her role as Antonella, as one of the lead actresses.

But the show is also facing various lawsuits: besides Ideas del Sur, Valeria Britos, the creator of the original script (when it was titled Ñeka), is also suing Dori Media.
