Victoria Beckham goes to bed naked. And she's got a very good reason -- her husband.

"You don't sleep with David Beckham," the 33-year-old Posh Spice tells Elle magazine in its January issue, on newsstands Tuesday. "I'm going to be naked if I'm getting in bed with him every night!"

The Beckhams and their three young sons moved to Los Angeles this summer when her soccer-superstar husband signed to play with the Los Angeles Galaxy.

"I'm very proud to be British, but here it's a lot more relaxed," she says. "It's the happiest as a family that we've ever been. I just love America."

She is now on tour with the newly reunited Spice Girls.

"I wanted my children to see that Mummy was a pop star," she says. "It was the last opportunity for them to stand in a crowd full of people screaming for the Spice Girls."

Beckham says she was never a "natural."

"It became very obvious from the start that I was never going to be the best singer or the best dancer or the best actress," she says. "You know, I've never been that good at anything, to be completely honest."

Still, she's a natural when it comes to keeping herself in the media spotlight, from her cutting-edge haircut to her high-profile marriage.

"I'm so camp! I'm such a gay man trying to get out," she says. "I don't give a (bleep) what anybody thinks."
