Kelly Osbourne has been arrested for allegedly slapping a woman in a Soho nightclub. Witnesses claim the radio DJ flew into a blinding rage after celeb gossip columnist Zoe Griffin insinuated that her fiancé, Luke Worrall, is a moron.

Zoe Griffin is said to have taunted Kelly Osbourne, 24, that Luke Worrall, 19, did not know what an earthquake was. That will totally do it every time.

The incident occurred in Londo's Punk nightclub in August. Kelly Osbourne went with her lawyers to a central London police station earlier this month.

A Met spokesman said: "We can confirm a 24-year-old woman attended a central London police by appointment on January 2. She was arrested for common assault relating to an alleged incident in Soho in the early hours of 29 August 2008."

Kelly Osbourne is free on bail until March after her arrest for allegedly smacking celeb gossip writer Zoe Griffin, after she allegedly called Luke Worrall an idiot.

Ozzy's daughter, who's giving Amy Winehouse a run for her money as the most unstable British celebrity, recently said she would "do anything" for Luke Worrall. Guess that means physically attacking anyone who looks at him weird.

This family's legal woes don't end there. In a separate incident, Los Angeles police are investigating Osbourne’s mother, Sharon, for allegedly attacking a contestant on the reality show Rock of Love: Charm School last month.

Megan Hauserman, 26, claims Sharon, 56, pulled her hair and scratched her until she was pulled away and restrained by security staff. Obviously.
