Happy birthday Christina Aguilera! Our top 6 Xtina moments of 2012 (PHOTOS)

Tonight is the much-anticipated finale of season 3 of The Voice, but coach Christina Aguilera is marking an even bigger milestone today: her birthday! That's right, the one and only Xtina is turning 32 years old today.

2012 has been a big year for the mom and singer. From her reality show judging duties to the the release of her seventh studio album, it seemed like Aguilera was EVERYWHERE this year. And as an avid viewer of The Voice and a fan of Aguilera's (well...most of the time), I decided to celebrate her birthday by rounding up a few of her best moments from the past year.

Happy birthday Xtina!
