She might've had 99 problems last night … but this performance wasn't one!
The songstress and Voice mentor took to the stage last night with finalist Chris Mann, singing The Prayer, which was originally done by Celine Dion and Andrea Bocelli!
Check out the STUNNING performance (above)!!!
Wow! Christina definitely proved why she's on the show in the first place…and Chris did great as well!

Um…okay then! LOLz!
Chris later also tweeted that last night was the "greatest night" of his life and that he was having a hard time pulling himself together after living out his dream!
