IN one of the most appalling and racist outbursts by a celebrity ever caught on tape, Mel Gibson drops the jaws of even the roughest among us. But this time, it’s got nothing to do with his anti-Semitic, alcohol-fueled words from his 2006 DUI bust.

Instead, it was revealed today in a series of audio tapes, Mel tells the mother of his 8th child, Russian musician Oksana Grigorieva that the way she dressed would get her “raped by a pack of n***ers,” according to RadarOnline.com.

In the tapes, Mel is also heard telling Oksana that he will burn down her home.

“You’re an embarrassment to me,” Mel tells her at one point.

“You look like a f**king pig in heat, and if you get raped by a pack of n***ers, it will be your fault.”

His outbursts are also littered with references to Oksana being a “whore” and a “c**t”.

In another lot of verbal diarrheoa, Mel says: “How dare you act like such a bitch when I have been so f**king nice.”

“I am going to come and burn the f**king house down…but you will blow me first.”

The two former lovebirds are in the middle of a bitter legal battle after Mel filed a restraining order against Oksana, and are fighting it out for custody of their daughter, Lucia. Published reports also state Oksana alleges Mel punched her in the face twice during a fit of rage, causing a concussion and knocking out two of her front teeth.

The tapes do not make it clear what the couple was arguing about when the conversation was recorded, although an insider revealed “Oksana’s motivation for recording this was to show Mel how mean he was, and because she feared for her life.”

“She wanted to get evidence that he was dangerous and violent.”

The source also says Mel has heard some of the audio and is trying hard to prevent their admittance at trial.

“Mel is doing everything he can to suppress this… they are the rantings of a mad man.”

We not sure if we want to hear the actual audio anymore…
