Mel Gibson is facing the possibility of legal action after a partygoer alleged the star attacked him during a night out at a Los Angeles club.
The Lethal Weapon star and his girlfriend Oksana Grigorieva, who is pregnant with Gibson's child, made a rare appearance at the launch of Playhouse on Wednesday (29Jul09).
The couple appeared to be enjoying themselves in the hotspot's VIP section until a magazine reporter, posing as a fan, took pictures of them, according to a report on
Gibson's security guards were said to have confiscated the camera and deleted the photos, prompting the relentless journalist to send a male friend to get another shot.
The actor allegedly flew into a rage and attacked the clubgoer before storming out.
A source tells Hollyscoop, "Mel approached the guy who tried to take his picture and ripped his shirt."
The website also claims the unidentified man then made his way to a local police station to file a report against Gibson.
It's not the first time Gibson has hit the headlines for troublesome behaviour - he was arrested in 2006 for driving under the influence.
