Kelly Osbourne has been arrested by appointment in relation to the incident back in August last year in which she is accused of slapping show business columnist Zoe Griffin.
Griffin says the altercation occurred because she had written a piece mocking Osbourne's boyfriend, model Luke Worrall, in which she claimed that he had had to ask how an earthquake was caused (which, had he wanted a complete geological explanation, isn't that stupid a question really, but anyway).
Writing in later article last summer, Griffin claimed that Osbourne had approached her in a nightclub and told her: "I have an issue with you. My boyfriend knows what an earthquake is and everyone has been laughing at him and he's upset". Griffin added in her article: "That's when I felt a hard slap to my right cheekbone".
A spokeswoman for Scotland Yard said: "I can confirm that a 24-year-old woman attended a central London police station by appointment at 3pm on January 2. She was arrested for common assault relating to an alleged incident in Soho in the early hours of 29th August 2008. She was bailed to attend a central London police station on a date in March".
No comment from the House of Osbourne.
