christina aguilera weight loss Christina Aguilera weight loss: Singer debuts svelte figure at 'Voice' premiereChristina Aguilera may not be returning to “The Voice” for Season 4, but the pint-sized songstress took to the red carpet at the premiere screening for the singing competition show — and showed off a rather svelte figure.

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.
