Kelly Osbourne had to have emergency hair extensions - because she's allegedly going bald. The raven-haired singer has reportedly started losing her locks because she dyes her hair so often. She had to dash to the stylist for expensive extensions before attending the 'Casanova' premiere earlier this week.

Kelly, who is now sporting blonde hair, is quoted in Daily Star newspaper as saying: "It was horrible. Because I've fiddled with my hair over the years, it started falling out in clumps. I had to get extensions for this premiere."

Last year, the 21-year-old - whose mother, Sharon, has spent thousands on cosmetic procedures - revealed she wants plastic surgery. The wild star, who was once admitted to hospital with depression over her poor self image, is set on spending thousands on improving her body.

Kelly confessed at the time: "I'm going to get lifted, sucked, tucked and Botoxed until my forehead doesn't move."
