O'z Born to pose naked!

Fire up the Photoshop boys, and plan on a late one.

Kelly Osbourne wants to pose nude in Playboy magazine. The rock heiress is prepared to bare absolutely everything for a centerfold in the men's publication - but would insist editors touch her up to make her look pretty and not so fat.

She says, "I'd go fully nude, but I'd have to have some airbrushing on my tits."

Meanwhile, she blames her privileged lifestyle for her substance abuse and depression because luxury living brings about extreme boredom.The 22-year-old has successfully overcome her demons following several spells in rehab - but is always on the lookout for the signs of a relapse.

She says, "It's so easy for me to fall back into depression. I think it comes with having money. I don't have to work. I could be sitting bored and depressed at home with a bag on my head." That last bit might be just the ticket for the photo shoot.
