Christina Aguilera flaunted a new slim figure at the Red Carpet for the screening of "The Voice" Season 4 in Hollywood on Wednesday sparking plenty of buzz on Twitter and other social media networks.

The 32-year-old singer showed off her new toned and sexy figure dressed in a black and white mini dress and Louboutin heels at the TCL Chinese Theatre event last night. Her legs looked more toned and her waist thinner, according to viewers. She also went for a more natura look with fresh makeup.

"Had a blast surprising @UsherRaymondIV @blakeshelton and @CarsonDaly at premiere screening of #TheVoice tonight. xo," Aguilera tweeted.

Aguilera was the center of attention at the premiere last night since Colombian singer and new-mom Shakira, who is replacing her for Season 4 of "The Voice," was absent.

Last night's appeareance came as a shock for many of her fans who have seen the singer with a much more curvy figure and heavy make up when she was a mentor of "The Voice."

Aguilera is currently taking a break from the show and was reluctant to talk about her come back with reporters.

"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," Aguilera told reporters, according to Us Weekly.
