In newly surfaced audio, a man who apparently sounds like Mel Gibson is heard crudely screaming at a woman, believed to be his ex Oksana Grigorieva.

"You're an embarrassment to me!" the man yells at one point, according to, which first broke the story Thursday. "You look like a f--king pig in heat, and if you get raped by a pack of n-----s, it will be your fault."

The man also 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 man is also heard calling the woman a "whore" and a "c--t."

Both Radar and claim the man is 54-year-old Gibson --- who famously spewed anti-Semitic slurs during a July 2006 DUI arrest -- but neither the actor nor his lawyers have confirmed their reports. Reps for Grigorieva, 40, also have not confirmed the reports.

The news comes as Gibson and Grigorieva are engaged in an ugly public battle over their daughter, Lucia, who was born in October.

On June 21, Grigorieva filed a restraining order against Gibson, alleging that he punched her in the face and knocked out her teeth Jan. 6. A Gibson source tells Us Weekly: "They got into it, but he absolutely did not injure her."

He then turned around and filed his own restraining order against Grigorieva, prohibiting her from speaking about certain aspects of their case.

They are both due in court July 20 over the restraining order.

Sources tell Us that Grigorieva's claims are a ploy for more custody — and cash. (His lawyer Stephen Kolodny tells Us the duo had reached an agreement in May that would lead to fifty-fifty custody.)

Grigorieva (who has son Alexander, 12, with actor Timothy Dalton) claims Gibson — worth a reported $900 million — is refusing to give her child support and forcing her to rack up debt. "I am having to live on credit cards," she told the U.K.’s Daily Mail June 26.

Last year, Gibson divorced his wife of 28 years, Robyn, with whom he has seven children. The two reportedly had no prenup, which means she walked away with about $450 million.
