Singer-actor Kelly Osbourne, who has been in rehabilitation centre seven times for drug and alcohol abuse, doesn't see anything wrong with having "occasional" drinks.

"I would never call myself clean, and I'm not in a treatment programme. I have the occasional drink, but now I can be happy without taking drugs," Osbourne told Closer magazine, reports femalefirst.co.uk.

The 31-year-old has also battled with her weight in the past, and now adopts an eating regime that sees her eat pizza for breakfast and oatmeal for dinner.

"I eat my fattiest meal in the morning. If I'm craving pizza, I'll have it for breakfast, salad for lunch, then oatmeal for dinner," she said.
