On the Season 4 finale of "The Voice," which crowned Danielle Bradbery as the winner, Christina Aguilera hit the stage and showed off her dramatic weight loss. The former show judge sang her hit song, “Feel This Moment,” alongside rapper Pitbull.

Prior to Tuesday night's performance on "The Voice," the duo performed the song at the 2012 American Music Awards, 2013 Kids' Choice Awards and the 2013 Billboard Music Awards.

Aguilera showed off her curvaceous figure in a black bodycon skirt and a mesh silver shirt that revealed a pink bra underneath. The 32-year-old singer first showed off her new curves last month at the Time 100 Gala in New York, where she rocked a cut-out, form-fitting black dress.

She noticeably gained weight after her divorce from Jordan Bratman in October 2010 . "I've been through my highs, I've been through my lows," Aguilera recently told Marie Claire magazine. "I've been through the gamut of all things in this business. Being too thin. Being bigger.

"I've been criticized for being on both sides of the scale. It's noise I block out automatically. I love my body. My boyfriend loooves my body. My son [4-year-old Max] is healthy and happy, so that's all that matters to me.”

Now, it looks like the singer has lost the weight and is keeping it off as she prepares to head back to "The Voice" next season after taking a break to refocus on her music. Latin-singing sensation Shakira, who had replaced Aguilera, is leaving the show after becoming a new mom to son Milan.
