According to online reports, actor Mel Gibson has come under fire after his most recent racist rant was caught on tape.

Gibson’s estranged baby mama Oksana Grigorieva recorded an argument between the two that turned ugly when Gibson said, “You’re an embarrassment to me. 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,”

RadarOnline.com has heard the tape, which also includes Mel telling Oksana he would burn down her home.

Mel’s profane outbursts are littered with references to Oksana being a “whore” and “c**t”.

RadarOnline.com first broke the story about how Mel, 54, and Oksana, 40, filed dueling restraining orders against each other under seal.

Published reports say Oksana is alleging Gibson punched her in the face twice during a fit of rage, giving her a concussion and knocking out two of her front teeth.

A source close to the situation says Oksana claims she was forced to tape Mel after he made a series of death threats.

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