Christina Aguilera weight loss: Singer debuts svelte figure at 'Voice' premiereAdd to Favorites | The Voice
Contrast her toned arms and legs with the picture, above right, of Xtina at the American Music Awards just over four months ago. Looking good, Aguilera!
She also offered some advice for her de facto replacement on "The Voice," singer Shakira, about working as a mentor/judge while also being a mom -- Shakira recently gave birth to son Milan.
"Everybody figures it out at their own pace, you know, it is a juggling act, it's a balancing act to take on your responsibility in front of the camera, and then be Mommy behind. Shakira seems like a tough girl that can hold her own, especially with these boys," Aguilera told reporters at the screening.
"The Voice" returns Monday, March 25 on NBC.
