Mel Gibson accused of assaulting daughter

London (ANI): In an explosive new tape, Mel Gibson"s ex-girlfriend Oksana Grigorieva has claimed that the actor assaulted her and their daughter Lucia in a fit of rage.

According to RadarOnline.com, Grigorieva is heard telling the Mad Max star, “You're acting as a crazy man right now and you have been for many, many months. And you hit me, and you hit her while she was in my hands! Mel, you're losing your mind. You need medication."

The fuming Hollywood veteran is caught on tape hitting back at Grigorieva, screaming,"You need a f****** kick up the a** for being a b*tch, c***, gold digging whore! With a p**** son! And I want my child, and no one will believe you! So f*** you!"
