Hugh Hefner's twin girlfriends KARISSA and CRYSTAL SHANNON are campaigning to get Kelly Osbourne to bare all in men's magazine Playboy.
The busty blondes are big fans of Ozzy Osbourne's offspring and they want her to strip for the publication.
Crystal says, "She's losing weight and she's blonde now. She looks good. I want to see what she looks like naked."
Karissa adds, "Yeah, we want to see Kelly Osbourne naked!"
And Hefner reveals that's not an impossibility, telling Eonline.com he has approached the pop star with an offer, adding, "Kelly would be happy to pose."
But she's not his girl of the moment - Hef wants sexy Transformers star Megan Fox to reveal all, stating, "Megan's a fox!"
