Reports: Racist Mel Gibson Rant Caught On Tape

Mel Gibson reportedly was caught on tape using a string of racist and derogatory remarks in a profanity-laced argument with ex-girlfriend Oksana Grigorieva.

Internet reports stated the audiotapes were made by Grigorieva. She and the actor are currently in the midst of a custody battle over their infant daughter, Lucia.

Radaronline.com reported Gibson is heard on the tape using the N-word and other derogatory phrases in the argument with Grigorieva, also reportedly threatening to burn down her home.

"You look like a f*king pig in heat and if you get raped by a pack of ni**ers, it will be your fault," TMZ. com said Gibson told Grigorieva on the tape.

According to TMZ.com, the tapes have been submitted to the judge in the couple's custody battle and are under seal. The website also reported that Grigorieva kept a number of "incendiary e-mails" that Gibson sent to her.

Grigorieva's attorneys declined to discuss the reports to People magazine Thursday, while Gibson's representative said, "I have no comment on, and furthermore no knowledge of, the credibility or authenticity of any alleged audiotapes."

In 2006, Gibson unleashed a now-infamous anti-Semitic tirade to police following a drunken-driving arrest. He later apologized for his "despicable" comments and "out of control" behavior.
