Christina Aguilera covers Maxim Maxim

Christina Aguilera is gracing the cover of Maxim's October issue, showing off her slimmed-down body in a white open shirt and black bra. “Hear the Voice, See the Body,” the headline reads, referencing NBC show “The Voice,” which features Aguilera as a judge.

This cover, while revealing, is less raunchy than her past three covers for the men’s publication, which have her either completely naked, on a bed, or in lingerie. Inside, the 32-year-old talks about how she defines being “sexy,” how your partner should go about introducing something different in the bedroom, foreplay and more.

Aguilera has had quite a busy past few months, getting her body back after noticeably gaining weight following her divorce from Jordan Bratman in October 2010. "I've been through my highs, I've been through my lows," Aguilera told Marie Claire magazine last year. "I've been through the gamut of all things in this business. Being too thin. Being bigger.

"I've been criticized for being on both sides of the scale. It's noise I block out automatically. I love my body. My boyfriend loooves my body. My son [4-year-old Max] is healthy and happy, so that's all that matters to me.”

But Aguilera has recently been working with a personal trainer and is on a strict diet. She has lost at least 20 pounds, according to some reports, and that is evident in her new photo spread.

Now, after taking a break to refocus on her music, Aguilera will rejoin fellow judges Blake Shelton, Adam Levine and CeeLo Green for the fifth season of "The Voice," which begins on Sept. 23. Latin-singing sensation Shakira, who had subbed for Aguilera, is leaving the show after becoming a new mom to son Milan.

“She did a beautiful job," Aguilera said about Shakira. "She has sweet, lovely energy.”
