Singer-actress Demi Lovato will appear this February at the Iquique Festival in Chile, where she will share the stage with Colombian pop star Juanes.
This will be the 19-year-old singer's third appearance in Chile, where in 2009 she sang for the Jonas Brothers, an American boy band, and performed solo in May 2010.
The contest kicks off Feb 3 with performances by a trio comprising Spain's Alex Ubago, Colombian Jorge Villamizar and Cuba's Lena Burke. Chilean singer El Gitano and reggae star Tito El Bambino will also perform.
Juanes and Demi Lovato will perform Feb 4, while the next day, the last day of the festival, will feature Chilean balladeer Myriam Hernandez and Mexico's Juan Gabriel.
Lovato, of Mexican, Irish and Italian descent, starred as Allison "Sonny" Munroe on Disney Channel's children's sitcom "Sonny with a Chance" in 2009 and 2010. She later underwent treatment for an eating disorder.
