A day after Mel Gibson was named a potential suspect in a domestic violence investigation involving ex-girlfriend,Russian singer Oksana Grigorieva, a recording of the actor spewing a "spewing a vile, hate-filled racist rant" was uploaded by RadarOnline.com at 4:31 p.m. on July 9.

Gibson, 54, is heard on the clip yelling at Grigorieva,40, "You're an embarrassment to me. You look like a f***ing bitch in heat, and if you get raped by a pack of n***ers, it will be your fault."

On the same day (within minutes, according to RadarOnline.com) as the recording was uploaded, a Reuters report uploaded at 6:25 p.m. said that Mel Gibson had been dropped by his agency William Morris Endeavor Entertainment. "Several studio executives have said in the wake of these disclosures that they consider the troubled actor too untouchable in the industry. 'I'd rather get engaged to Lindsay Lohan than have anything to do with him,' one studio chief said," reported Reuters.

Gibson and Grigorieva are currently in a custody battle over their 8-month-old daughter. The two first admitted they were in a relationship right after Gibson's wife, Robyn, filed for divorce last April. The divorce is pending," reports AFP. "Oksana has reportedly taken out a  restraining order against him after she claimed he got "extremely violent" and punched her twice in the face. Gibson's lawyer described this exchange as a "loud argument." reports EOnline.com.

Radaroline.com reports "Oksana taped Mel because she was afraid for her life after he threatened to kill her, a source told RadarOnline.com. And on one part of the tape Mel tells her: "I am going to come and burn the f**king house down... but you will blow me first." Here's an  excerpt of the tape's transcript:

"The tape begins with Mel berating Oksana about her breast feeding because she has implants.

'So you're not lying to me about fake t*ts?' he says.'I never have,' she answers. This is the buildup to his racist rant.Mel gets enraged and tells Oksana that she lied to him. When she denies it, he says about her breasts: 'They look ridiculous. Get rid of them why don't you.' But Oksana tells him it's none of his business and Mel rants, 'Keep them if you want, they look stupid. Keep 'em if you want. Look stupid. See if i give a f*ck. They look like a Vegas whore. And you go around sashaying in your tight clothes. I won't stand for that anymore.'

In 2006, Gibson was arrested in Malibu on suspicion of drunken driving, during which he unleashed anti-Semitic and sexist insults. He apologized later, saying he had been grappling with alcoholism for all of his adult life.
