Los Angeles: Fashion designer Kelly Osbourne says some men just want to have sex with her because she is famous. The 31-year-old daughter of Black Sabbath frontman Ozzy and TV show host Sharon admitted that she can be quite wary of men because some are only interested in her for her fame, reports femalefirst.co.uk. She said: “People always want to say they've f***ed Ozzy Osbourne's daughter. Boys tell me. I could have been born like Quasimodo and I still would have been a conquest. And you can tell, when someone's having sex with you, if that's their reason. It's a disgusting, awful feeling. I am quite defensive when I talk to guys. "I am mouthy, but I will tell you the truth. I am pint-sized, but a little bit chubby. I'm still trying to figure the rest out." Kelly - who has been in rehab seven times - has been through some tough times in her life, including her brother Jack's multiple sclerosis diagnosis, her mother's cancer battle and her father Ozzy's near-death experience after a quad bike crash, but says she has emerged stronger than ever.
