Christina Aguilera 'comfortable in just a jersey and boy's underwear'

Christina Aguilera is flaunting her figure in the newest issue of Maxim.

For the October cover, the 32-year-old singer and mentor on The Voice strips down to just a black bra, white underwear and a white dress shirt. Inside the magazine is a pictorial that includes Aguilera in a skin-tight red dress and another in high-wasted briefs and a matching bra.

Everybody's posing nude!

"I'm such a down-to-earth girl, I'm comfortable in just a jersey and boy's underwear," Aguilera says. "Trying too hard to be sexy is the worst thing you can do. Sexiness should be effortless."
