Christina Aguilera was spotted flaunting her major weight loss at an NBC press event on Saturday. Over the weekend the returning "The Voice" coach had jaws dropping as she sported a form fitting pink mini dress.

The "Hurt" singer made a statement on the red carpet of the event wearing a clingy pink dress that showed off her tan legs, while her long blonde locks spilled down her back in loose waves, according to Us Weekly.

A source told the magazine that Aguilera managed to lose weight with a combination of healthy eating and working out. "It's more of a mind-body thing for her," the source said.

"She believes in exercise that she enjoys, doing strength work as opposed to intense cardio."

This is not the first time the singer has made headlines about a dramatic weight loss. Back in June she was seen showing off a slimmer figure. Aguilera displayed an estimated 20-pound weight loss on "The Voice" season 4 finale when she performed the hit song "Feel this Moment" with Pitbull.

Over the weekend the singer told reporters, "I'm the type of person that I cannot live in front of a camera 24 hours a day."

"I have to take breaks and stay connected with myself, and I think it's important so that you can then be your best on-camera and find your own happiness with it."

Just last fall, Aguilera faced a lot of criticism over her weight gain and surprisingly her co-coach, Adam Levine, who she often argues with on the show defended the star.

Back in October Levine stuck up for Aguilera telling reporters, "The one thing about culture right now, celebrity culture particularly, is people feel like they can just say nasty things about other people, whether it's Christina or whether it's me."

"She gets a lot and it pisses me off. Of course I have her back and of course I defend her."

He went on to say, "It's not cool. I've never liked it."

"I think it's horrible and I'll totally defend her when people say things like that because it's no one's business."

According to E! News, a source said that the singer is committed to a body makeover, "[She's] making herself a priority, trying new exercises and trying things she loves and enjoys rather than stuff to just 'lose weight.' This is really from the inside out."
