Christina Aguilera's Stunning Makeover

Christina Aguilera made a jaw-dropping comeback anyway at an event for the NBC reality show on Wednesday, March 20. Making a surprise appearance on the red carpet for the season-four premiere screening at the TCL Chinese Theater in L.A., the "Your Body" singer, 32, turned heads in a little black-and-white dress that showed off a noticeably slimmer figure, not to mention Aguilera's toned, sexy legs, accentuated by high Louboutin heels.
Aguilera, whose over-the-top style, curvy figure and dramatic makeup provided frequent comment during her seasons as a mentor on the show, also tried out a more natural, fresh-faced beauty look.

Speaking briefly with reporters outside the theater, Aguilera was coy on when, and if, she'll return to the show. "I can't say anything right now. I can only do what feels right for me in the moment and right now what’s important for me, and this is why I love the show, and why I’m coming back in support," explained the Grammy winner. With Aguilera and fellow mentor Cee-Lo also out for season four, they've been replaced by newcomers Usher and Shakira to join returning veterans Blake Shelton and Adam Levine.
