Christina Aguilera is back!

All eyes were on the 32-year-old "Your Body" singer when she appeared at an NBC press event in Beverly Hills on Saturday to promote her big return to "The Voice." Not only was the show mentor showing off her slim, trim new frame, which there has been buzz about in recent months, but she also unveiled a serious style makeunder.

Wearing a curve-accentuating pink minidress with a flirty ruffled bottom, Aguilera looked like she did in her early days. The subtle, natural look (including her barely there makeup!) was a departure from how we've come to expect her on the reality series. There were no rhinestones, bustiers, hotpants, spiked berets, or other attention-grabbing fashions which have become part of her signature style on "The Voice." Just a beautiful, fresh-faced Aguilera, looking tanned, toned, rested, and ready for Season 5.

This isn't the first inkling we've had that her return (after sitting out Season 4) will bring new things. Earlier this month she rocked another more demure look at a press junket for the show. That style, which more business chic than rock star, had her in a hip-hugging black and white skirt and a black blouse that was significantly more conservative than her usual over-the-top fashions.

"I'm the type of person that I cannot live in front of the camera 24 hours a day," the singer told the Television Critics Association panel on Saturday about her hiatus from the show and new look. "I have to take breaks and stay connected with myself. I think it’s important so that I can then be [my] best on camera and find [my] own happiness with it."

Aguilera said her time off was also about spending time with her son, Max — and noted that when she's home with the 5-year-old, her personal style is stripped down and very simple.

"I'm a mom and … the cameras go off, I go home, I put on sweats and a T-shirt. The red lips come off. I check out and I’m mom," she said. "I needed some time to do that. He starts kindergarten this fall. ... I wanted to also, for myself, [to] have a moment … for me. It's really important to take that time in this business, when everything’s give, give, give — especially when you’re on camera so much — you need to take it back for a second and bring it back to yourself and just realign some things. I’ve been on a really incredible journey the past six months and I just feel revived."

Well, not only does she feel revived, but she also looks it. And we can't wait to see her with Adam Levine, Blake Shelton, and Cee Lo Green when "The Voice" returns on September 23.
