Mel Gibson is at it again...

Radar Online wrote:In one of the most explosive, racist and vile outbursts by a celebrity ever caught on tape, Mel Gibson told the mother of his love child that the way she was dressed would get her "raped by a pack of n***ers," RadarOnline.com has learned exclusively.

It's a shocking and blockbuster development in the couple's bitter legal battle, and Mel's disgusting words are on audio tape. His racist, misogynist statement is one of the secrets lurking in his war with his former girlfriend Oksana Grigorieva.

RadarOnline.com has heard the tape, which also includes Mel telling Oksana he will burn down her home.

Drunken Mel previously shocked the world with his anti-Semetic comments when busted for DUI. Now, the new racist outburst has taken the Oscar winner to an even deeper low.

His outburst came during a series of explosive arguments with Oksana, mother of his infant daughter Lucia. They have been battling in court, with documents under seal, for the past several weeks.
