KARMA IS A B!TCH! MEL GIBSON LEFT HIS WIFE OF 28 YEARS FOR THIS CHICK & LOOK WHAT HE GETS! SHE SECRETLY TAPED HIS RANTS WHERE HE DROPPED THE N WORD!

Loose cannon Mel Gibson is proving he's just the opposite of what women want.
The bad boy actor was reportedly caught on tape exploding in a racist, profanity-laced tirade at ex-girlfriend and baby mama Oksana Grigorieva, according to gossip site RadarOnline.com - just the latest and nastiest development in the couple's bitter legal battle.

"You look like a f---ing pig in heat," Gibson reportedly says in the recordings. "If you get raped by a pack of n----rs, it will be your fault."

A source tells RadarOnline that a terrified Grigorieva taped Mad Mel's outbursts after the star bullied her with multiple death threats.

"She wanted to get evidence that he was dangerous and violent," says the source. "Oksana's motivation for recording this was to show Mel how mean he was, and because she feared for her life."

Radar's source reveals that Grigorieva plans to use the tapes if she is forced to face off against Gibson in court.

The feuding former lovers have both filed restraining orders against each another in recent weeks. Oksana has alleged that an angry Gibson hit her in the face, knocking out two of her teeth and giving her a concussion.

Meanwhile, Gibson filed his own court order, which reportedly intended to keep his ex from revealing certain information.

Radar's source claims the actor has heard two of the recordings and is in a panic. "Mel is doing everything he can to suppress this," says the insider. "They are the rantings of a mad man."

In addition to sickening threats, the audio clips are said to be full of obscene, misogynistic language.

"I am going to come and burn the f---ing house down," Gibson allegedly tells Grigorieva. "How dare you act like such a b---h when I have been so f---ing nice?"

Lawyers for the couple went at it in court Thursday, reports gossip site TMZ, trying to get to the bottom of how the secret recordings were leaked. Sources told the website that Grigorieva's lawyers "vehemently denied" she spilled the tapes.

Attorneys for Grigorieva declined to address the reports, People.com reports, though Gibson's rep said, "I have no comment on, and furthermore no knowledge of, the credibility or authenticity of any alleged audio tapes."

Gibson has a long history of using his tongue as a lethal weapon. He famously went to rehab in 2006 after his alcohol-fueled anti-Semitic rant went viral, in which he ranted to police that "The Jews are responsible for all wars in the world."
