Christina Aguilera is off our small screens right now, on hiatus from 'The Voice.' But she has returned to her Latin roots by teaming up with Mexican singer Alejandro Fernandez for a track.

For their duet, they cover Miguel Gallardo's 'Hoy Tengo Ganas de Ti" from 1975.

It's sultry, and Xtina's voice is bold and beautiful in whatever language she sings. While her recent album 'Lotus' tanked, she's still got the voice of an angel.
