Christina Aguilera walked on the red carpet seemingly slimmer on Wednesday for The Voice's NBC promo event that made fans turn heads.

Former judge of The Voice, the singer arrived at the Los Angeles TCL Chinese Theater in a black and white dress and Christian Louboutin heels, showing off her tanned, toned legs.

"Xtina" has gotten a lot of negative media attention in the past for her unstable weight control. But recently, Aguilera said she would not give in to the pressure to be skinny again.

"Christina is happier and more relaxed nowadays," said to an insider who spoke to People magazine.

Being that Aguilera is no longer committed to working for The Voice, she's making more time for herself, trying new types of foods and exploring new methods of exercise, "not for diet or weight, but more for her mind and well being and overall sense of good health," said the source.

Some celebrities believe some of the weight loss may have stemmed from her cutting back on alcohol consumption.

When asked if she will be returning as a judge for The Voice, she said, "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," according US Weekly.
