The Voice judge strutted her stuff on the show's stage last night as she performed "How I Feel" with Pitbull.
Wearing a black beaded body suit, Xtina made it very clear that her body is back in fighting form as she worked the stage for the performance.
Christina started off the song with a more conservative ensemble, but it wasn't long before she stripped down to next-to-nothing and brought the sexy back.
The pop star took last season off from the show so that she could focus more on her son, but it looks like she spent some serious hours in the gym, too!
We're so happy to see her back on the stage and we have to give her major props for whipping her body back into shape like that.
