It is the audio tape that could destroy Mel Gibson.
The Hollywood star is accused by Oksana Grigorieva of hitting her and their infant daughter in an explosive argument recorded on tape, obtained and released exclusively by RadarOnline.com.
“You hit me, and you hit her (Lucia) while she was in my hands! Mel, you’re losing your mind. You need medication,” Oksana tells him on the newly released tape.
And Mel, raging at Oksana, is caught on audio telling her: “I want my child, and no one will believe you.”
