Mel Gibson calls Oksana Grigorieva a 'psycho' -- and worse -- on tape [UPDATED]

mel-gibson-oksana-.jpgIt's been four silent years since Mel Gibson's infamous anti-Semitic rant. But the actor/director still has a racist potty mouth.

Mad Mel, who was shunned by Hollywood after he blamed the "f***ing Jews" for all the wars in the world in a drunken rant to a police officer in 2006, is at it again.

He's left the Jews out of it this time. But he uses the N-word and the C-word when he curses, berates and threatens his ex-girlfriend Oksana Grigorieva, the Russian singer and mother of his infant daughter. And according to Radaronline, it's all on tape!
