Oksana Grigorieva, Mel Gibson's estranged ex-girlfriend, has responded to the actor's scathing rant to Deadline which alleged that the tapes of his racist rants were edited, announcing that the authenticity of the tapes has been proven authentic and completely unaltered by experts.

"We have heard Mel Gibson's irresponsible accusations that his vicious racist rants were in fact edited. They were not," Grigorieva's rep Steve Jaffe said in a statement obtained exclusively by OnTheRedCarpet.com. "The recordings have been authenticated and proven to be completely unaltered by Kirk Gibson a nationally renowned audio expert with degrees from Yale and Stanford Universities."

Kirk Gibson also accounted for the sound quality and matched Gibson's voice to previous samples.

"I was not able to identify indications of editing in the recordings at all. In my professional opinion as a forensic audio examiner, I conclude that the recording have not been modified, and can be considered authentic," the expert wrote in an official document.

Grigorieva's representative also issued a statement inferring that Gibson did the interview as press for his newest film, "The Beaver" and confided that the couple had previously agreed to be civil.

"We thought we had reached agreement with Mr. Gibson not to attack each other in the press," Grigorieva's rep Jaffe said in a statement. "We were clearly wrong. We believe that Mr. Gibson is attempting to stir up controversy about himself in order to promote his failing beaver movie. This is a tactic that he has used in the past with another movie and we find it both reprehensible and sad."

In Gibson's interview, he said that he had never treated anyone badly based on gender, race, religion or sexuality "period."

"I don't blame some people for thinking that though, from the garbage they heard on those leaked tapes, which have been edited," Gibson told Deadline. "You have to put it all in the proper context of being in an irrationally, heated discussion at the height of a breakdown, trying to get out of a really unhealthy relationship. It's one terribly, awful moment in time, said to one person, in the span of one day and doesn't represent what I truly believe or how I've treated people my entire life."

Gibson, 55, recently promoted his new movie "The Beaver" with his friend and co-star Jodie Foster. The film aired at the South by Southwest Film Festival in March and is set for a limited release on May 6, 2011.

On March 11, Gibson pled no contest to charges of misdemeanor battery against his ex-girlfriend Oksana Grigorieva from a January 2010 confrontation. The actor was sentenced to informal probation for 36 months, 16 hours of community service with Mending Kids International, a 53-week domestic violence program, continued mental health counseling and a $400 domestic violence fine. If he violates his probation, Gibson could face up to a year in prison.

Gibson's lawyer made it clear that the actor was not admitting guilt but was "entering into plea because it's in the best interest of his children."

Grigorieva, a 40-year-old Russian musician, gave birth to Gibson's daughter, Lucia, in October 2009. They broke up in April 2010. The following summer, she accused him of punching her in the face the previous January at his Los Angeles home.

A recorded racist, sexist and explicit rant Gibson is said to have made against Grigorieva over the phone was then released and posted on the website RadarOnline.

Gibson has denied he punched her and said in court documents filed in June 2010 that he slapped Grigorieva during the confrontation in a bid to protect their baby, who she was holding in her arms at the time.
