'I'm such a gay man trying to get out,' she adds
Victoria Beckham sleeps naked because she loves the feel of husband David's skin.
The Spice Girl shuns nightwear so she can feel the soccer star's athletic physique next to her body.
Victoria - who has three sons, eight-year-old Brooklyn, five-year-old Romeo and two-year-old Cruz, with David - said: "I sleep naked. I'm going to be naked if I'm getting in bed with him every night!"
Victoria - who has her own clothing line, DVB, and a his and hers fragrance line with David - also slammed her celebrity rivals, including Paris Hilton, who she claims have no input into their respective empires.
She added: "There are so many, and I hate the word celebrities, clothing lines and fragrances, and most of them have nothing to do with it."
The 33-year-old style icon, who is currently on the Spice Girls reunion world tour, joked her love of fashion comes from her inner "gayness".
She joked to America's Elle magazine: "I'm so camp! I'm such a gay man trying to get out. I don't give a f**k what anybody thinks!"
Victoria graces the cover of the January 2008 edition of the publication, and also appears in a shoot inside the magazine, which was shot in Paris in October.
The Spice Girl is pictured in several high-couture outfits, including a sci-fi inspired silver mini-dress with platform silver shoes and a red-ruffled gown with towering black heels.
