Xtina Suprises The Voice Contestant With Mary J. Blige Duet!

That’s one way to win over a contestant!
On tonight’s episode of The Voice, Christina Aguilera shows off her own pipes with a lucky contestant.
Xtina says she was so inspired by the contestant’s rendition of Mary J. Blige’s I’m Going Down that she needed of her own.
The sound crew happily obliged!!!
Check out the video above to hear Xtina and one very lucky (and shocked!) contestant sing an impromptu duet of the ages!
Xtina just turned this girl’s world upside down!
