Mel GibsonIn the midst of being investigated for domestic violence, Mel Gibson has a very obscene leaked phone call on his hands.

RadarOnline.com posted Gibson's obscene rant to the mother of his child and ex-girlfriend Oksana Grigorieva, who has accused the 'Bravehart' star of hitting her, a claim Gibson denies.

"So you're not lying to me about fake t---?" he begins. ""They look ridiculous. Get rid of them why don't you."

"You go out in public and it's a f-----g embarrassment to me. You look like a f------ b---- in heat. And if you get raped by a pack of n------ it will be your fault. Alright? Because you provoked it. You are provocatively dressed all the time with your fake boobs that you feel you have to show off. I don't like it. I don't want that woman. I don't want you. I don't trust you. I don't love you," Gibson yelled.
