Christina Aguilera debuts new slim figure at Time 100 Gala

Christina Aguilera showed off her slim new figure Tuesday at the Time 100 Gala.

Aguilera, who has said she "got tired of being a skinny white girl" and famously defended her curves by telling her label they were "working with a fat girl, know it and get over it," was one of the honorees in this year's Time 100 list of Most Influential People in the World.

The magazine announced Aguilera's presence on the list on April 18 with a short essay in which the 32-year-old singer was praised by Canadian singer Celine Dion.

"The first time I heard Christina Aguilera sing, I was totally blown away. I love the way she sings. Her tone is beautiful, and her voice has got so much power, yet so much sensitivity -- and technically, I think, she's flawless," Dion wrote. "Without a doubt, she's one of the most talented artists the world has ever seen and heard, and I think she’s going to continue to amaze us for many, many years to come."

Aguilera responded to the honor with a tweet in which she thanked both Time and Dion.

"I'm very honored to be part of the #TIME100 list and for the wonderful words from Celine Dion. Thank you! XoXtina," she wrote.
