Has Kelly Osbourne really been arrested for smacking a gossip columnist in a London nightclub?

According to reports, that's true! The reality star, 24, allegedly hit journalist Zoe Griffin after Griffin reportedly wrote some less-than-flattering material about Kelly's main squeeze, Luke Worrall.

Griffin told Reuters, "Kelly shouted loudly in my ear, 'I have an issue with you. Everyone has been laughing at my boyfriend.' Then I felt a hard slap."

A spokesperson for the Met police in the U.K. said, "We can confirm a 24-year-old woman attended a central London police station by appointment on 2 January. She was arrested for common assault relating to an alleged incident in Soho in the early hours of August 29, 2008. She has been bailed until a date in March."
