It's the holiday season, and you know what that means. Our very favorite Christmas song, Mariah Carey's 1994 classic "All I Want for Christmas Is You," is taking over the airwaves! Nearly 20 years after the release of her holiday hit, Mariah teamed up with the Roots, Jimmy Fallon and a chorus of adorable kiddies for a live remix of the tune on "Late Night With Jimmy Fallon."
This got us thinking about another adorable kid who once killed it with a cover of Carey's Christmas favorite; Joanna from the beloved holiday movie, "Love Actually."
Olivia, now 20, has been working on her singing and acting careers. Since "Love Actually," she's had roles on "The Tracy Morgan Show" and "Zoey 101," and is currently voicing characters for the animated series "Phineas and Ferb" and "Adventure Time." As for her music, she's been posting covers on YouTube and sharing her own music via Facebook and Myspace.
