Her accusations against Mel Gibson - physical violence, coupled with racist and sexist tirades - are absolutely sickening. But is Oksana Grigorieva telling the truth?
That's what law enforcement officials wonder, having "serious concerns" over Oksana's credibility in connection with her domestic violence claim against Gibson.
We've spent plenty of time detailing her accusations against Mel, including his viciously profane, racist tirade. But the counter-argument is she's lying for money.
Moreover, sources are saying that Mel Gibson has emails and other evidence that Oksana "tried to extract money from Mel in return for the [explosive] tapes."
Oksana Grigorieva apparently recorded several explosive arguments with the actor, with whom she split in January and has an eight-month-old daughter, Lucia.
BITTER BATTLE: Who's telling the truth, Mel or Oksana?
Investigators are concerned that Oksana had contact with lawyers and judges while she negotiated a visitation agreement with Mel but never once contacted police.
Oksana was represented by lawyer Eric George, the son of California Supreme Court Justice Ronald George, to handle the visitation case surrounding Mel and Lucia.
She endured two full days of mediation in May, conducted by two former judges, one of whom a former federal prosecutor, and negotiated a visitation agreement.
The agreement, signed by both Oksana and Mel, gave Mel full visitation rights and future joint legal custody of their daughter. But soon, she sang a different tune.
Last month, Oksana refused to give Mel his visitation rights and alleged abuse for the first time. Police are currently investigating Mel Gibson for domestic abuse.
