Christina Aguilera Weight Loss: Singer Shows Off Slimmer Body At 'The Voice' Screening [PHOTO]

Wearing a large belt that accentuated her waist, the 32-year-old singer looked more toned than she has in recent months.

Aguilera divorced Jordan Bratman in October 2010, and noticeably gained weight since.

"I've been through my highs, I've been through my lows; I've been through the gamut of all things in this business. Being too thin. Being bigger," Aguilera said in an interview with Marie Claire magazine in October.

"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,” she continued.

Aguilera has been dating Matthew Rutler since 2010.

Based on her appearance at the screening for the hit talent competition, it seems Aguilera has been sticking to a healthier diet and exercise regimen in recent months.

Aguilera, who was a judge on the show, left “The Voice,” as did singer Cee Lo Green, in December, as they wanted to focus on their singing careers. Usher and Shakira went on to replace the artists. Blake Shelton and Adam Levine remain as judges on the reality competition.

Aguilera currently has a song out with Cuban-American rapper Pitbull titled “Feel This Moment,” and looks noticeably trimmer in the music video.
