Gibson Planning To Reveal All About Ex's Alleged Extortion Plans

Gibson is currently at the centre of a police investigation in Los Angeles after Russian singer Oksana Grigorieva - the mother of his baby daughter Lucia - reportedly obtained a restraining order against Gibson, amid claims he punched her and knocked out a tooth during a heated altercation in January (10).

Gibson denies the allegations and is now planning his own attack - sources tell People.com Gibson will be presenting evidence to the authorities which will prove Grigorieva tried to extort money from him, and threatened to leak the heated phone recordings to the press if he didn't pay up.

In an extract of the taped audio, released by RadarOnline.com on Friday (09Jul10), a voice resembling Gibson's can be heard raging about his girlfriend's alleged breast implants, telling her she looks "ridiculous" and orders her to "get rid of them".

He also accuses Grigorieva of looking like "a Vegas whore".

The rant is full of expletives and unsavoury language and ends with the male voice saying, "I don't want you. I don't trust you. I don't love you."

Meanwhile, Gibson has been dropped by the William Morris Endeavor Entertainment agency, according to The Hollywood Reporter.

His spokesman insists the decision has nothing to do with the actor/director's latest scandal, stating Gibson has been planning to go solo following the death of his longtime agent Ed Limato: "At this point he doesn't seem to be in need of an agent."
