The Spice Girl reveals all.

VICTORIA BECKHAM may be known for her over-the-top style, but there's one place the fashionista opts for the bare minimum -- the bedroom. Posh says she sleeps in the buff!

"I sleep naked," she's quoted as saying in the new Elle magazine. "I'm going to be naked if I'm getting in bed with [DAVID BECKHAM] every night!"

Of course, in public the sexy singer always keeps herself covered in a designer label -- or something from her own clothing line. When it comes to her fashion label she says that unlike many celebs, she's very hands on.

"There are so many -- and I hate the word celebrities -- clothing lines and fragrances, and most of them have nothing to do with it ... I could bore you to death with zips and dyes and all sorts of things. I go to denim factories and come out completely blue! I work seven days a week. And I so love what I'm doing," she adds. "I could go shopping all day, which is what a lot of people think that I do. That's their perception -- that I'm a miserable b**** and go shopping all day and boss David about."

As for being an oft-mocked celebrity icon, "I'm so camp! I'm such a gay man trying to get out. I don't give a s*** what anybody thinks!" she says.
