It's Mad Max vs. James Bond.

Oksana Grigorieva confessed to ex-lover, Timothy Dalton, that Mel Gibson struck and choked her after the concerned James Bond star noticed the mother of his child was bruised, RadarOnline.com has exclusively learned.

What's more, Grigorieva told her lawyer the Licence to Kill star will testify against Gibson in their case, according to correspondence obtained exclusively by RadarOnline.com.

Oksana Grigorieva told her lawyer she planned to walk away from a multi-million dollar settlement and see "where the chips might fall" in court unless her former lover Mel Gibson was stripped of some of his custodial rights over their baby daughter Lucia, RadarOnline.com has exclusively learned.

What's more, the Russian musician declared the Oscar winning director/actor was "bluffing" and claimed she was forced to sign a $15 million peace deal "under duress" from her own legal advisors.

In sensational new evidence, RadarOnline.com has obtained correspondence Grigorieva, 40, sent Eric George, the son of California's former chief justice, as the latter duked it out with Gibson's camp during the height of negotiations to keep the case secret.

She recently hired Sorrrell Trope as her new lawyer – but RadarOnline.com is reporting exclusively that she first met with him – and rejected hiring him – the day after failed mediation talks in May.

“Oksana was furious at how she was treated during the mediation,” said a source, with intimate knowledge of the case.

“At the time, she was being represented by Eric George, but after the talks broke down, Oksana met with Sorrell Trope and then celebrity divorce attorney Stacy Phillips.

“Oksana didn’t sign with either of them because she said they were asking for a $20,000 retainer before commencing work on the case.

“In the end, she told George that she wanted new counsel and he ultimately introduced her to Manley Freed and Marci Levine.”

However, Grigorieva axed Freed and Levine on Monday and appointed Trope to the case, who has represented celebrities including Anna Nicole Smith and Britney Spears.

It is the second time that the Russian-born singer-songwriter has changed legal teams during the course of the child custody case.

Grigorieva is seeking to increase the monthly child support payments that she receives from Gibson.

Comment is being sought from Trope.

Oksana Grigorieva's former attorney Eric George is going to be questioned by the Los Angeles District Attorney's Office and the Los Angeles Sheriff's Department investigators in regards to the extortion case between Oksana and Mel Gibson, RadarOnline.com has learned exclusively.

Gibson claims his ex threatened to leak recordings of him saying racist and bile-filled remarks unless he paid her a large sum of money.

Under California law, anything that was discussed at mediation doesn't fall under the attorney client privilege. "Eric hasn't spoken to the district attorney's office, nor law enforcement, yet,” a source close to the situation told RadarOnline.com. “Those arrangements are still being made. Eric plans on cooperating with the investigation without compromising the attorney-client agreement."

As RadarOnline.com previously reported, the extortion case against Oksana was turned over to the Los Angeles District Attorney's Office several weeks ago. Deputy District Attorneys John Lynch and Simone Shay are handling the case and no decision has been made yet about what charges if any Oksana or Mel will face. "Simone is a no-nonsense prosecutor," the insider said. "This case will be handled with professionalism by the District Attorney's office."

The insider went on to say, "Anything that Oksana told Eric directly, does fall under the attorney client privilege. However, if that information was then discussed at the mediation, George would be compelled under the law to answer appropriately. The mediation hearing wasn't videotaped nor audiotaped."
