Reality TV star Kelly Osbourne has reportedly refused to pose nude in Hugh Hefner's Playboy magazine. Earlier, the Playboy music mogul Hugh Hefner had said that Kelly would be happy to pose. Even Hefner's twin girlfriends, who are big fans of the former wild child, expressed their hope to see her naked.

Kelly Osbourne is looking slimmer and trimmer than ever. Kelly, who is romancing her boyfriend Luke Worrell, said to have dropped from a size 12 to an 8 in weeks with her intensive training. Last week, Hefner's girlfriend Crystal said, "She's losing weight and she's blonde now. She looks good. I want to see what she looks like naked."

Osbourne is currently competing on TV's "Dancing With The Stars. She has politely declined the chance to show off her curves. Even her representative has denied Hefner's talks with her. He said, "Hef didn't ask her."
