It appears Christina Aguilera is embracing her Latin roots once again…

The 31-year-old half-Ecuadorian singer appears on the soundtrack for Will Ferrell’s telenovela-inspired film, Casa de Mi Padre.

Aguilera’s flamenco-inspired track, which opens the comedy film, features Spanish guitars, brass trumpets and synthesizer-free vocals.

Casa marks The Voice mentor’s first true return to Spanish-language singing since her contribution to the Dirty Dancing: Havana Nights soundtrack, “El Beso Del Final,” in 2004. In addition, her most recent album, Bionic, featured the bilingual track “Desnudate.”

But nearly 12 years ago, Aguilera took the biggest stab at celebrating her Latin roots… She released a full-length Spanish album in 2000 entitled Mi Reflejo. Containing Spanish versions of songs from her English debut and new Spanish tracks, the album went on to win the Latin Grammy for best female pop vocal album and went No.1 on the Billboard Latin charts for a record 20 weeks.

Entitled “La Casa,” Aguilera’s new track was released digitally this week.

Meanwhile Casa de Mi Padre opens nationwide on March 17.
