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.

"You're an embarrassment to me," Mel tells her at one point.

"You look like a f***ing pig in heat, and if you get raped by a pack of n***ers, it will be your fault."[/center]
