TMZ has obtained emails Oksana Grigorieva sent Mel Gibson just before their mediation, which Mel's lawyers believe are proof of extortion. Oksana claims she has "Too much evidence, my dear."
According to court documents, Oksana sent the emails on May 2, two weeks before she and Mel went into mediation which resulted in a $15 million package for Oksana and Lucia.
In the email, Oksana accuses Mel and his family of leaking stories to the media about their breakup -- specifically "...they claim that you dumped me."
Mel's lawyers believe the emails show Oksana as a manipulator who was not fearful of Mel at all, but rather someone who was scheming to extort millions.
Oksana writes, "Does your family think that my modesty and class could pass for stupidity?" She adds, "Do they think, i will let them carry on with ruining my reputation, which was unblemished before i ever layed eyes on you?"
Then Oksana gets serious: "The facts are stubborn things, the information is power, you told me so yourself."
Then, far from being scared, it seems Oksana wanted Mel back, writing, "Untill this morning I was still missing you so much and secretly wanted and hoped for us to be together again."
Oksana accuses his wife, Robyn, and daughter, Hannah, of waging a "silent war" against her, complaining, "Are you a little boy, or are you a man? Why are you so easily influence by your mommy Robyn?"
Oksana adds "...my lawyers also told me that tom Hansen said i woudn get a penny and more importaunly, my lawyers warned me that ur laywers are capaple of false fabrication about me in press, i.e., an unfit mother, a prostitute etc. so you can have the baby and I get to go to my f...ing moth hole as u told me."
Oksana talks about taping Mel and makes a big statement Mel's lawyers have seized on: "Too much evidence, my dear."
