Fourth Mel Gibson Rant Released: Threatens to Burn Down House

Another shocking audio tape has been released in which Mel Gibson threatens girlfriend Oksana Grigorieva with violence, saying, "I'll burn the [expletive] house down."

In a recorded conversation which captures the actor and Grigorieva that was obtained by RadarOnline.com, Gibson screams every word like a verbal punch, spouting off obscenities in a rage over an apparent missed Jacuzzi date that the new mother missed after dozing off.

He shrieks, "I should've woken you up ... how dare you!" followed by a string of misogynistic demands. Between shouts of rage, he pants heavily.
