Mel Prepared To Drop A Bombshell On Oksana

It’s about to get ugly uglier.

As criminal investigations into both Mel Gibson and Oksana Grigorieva are coming to close, Mel’s lawyers have one more ace up their sleeves to try and turn things to their favor. Sources are reporting that Mel’s team is prepared to show evidence that Oksana bribed a witness into telling her side of the story.

Though this alleged paid off witness remains unknown, insiders say that this person is relevant in both the criminal and custody cases. Supposedly, one of Mel’s lawyers will be meeting with Deputy District Attorney John Lynch this week to present evidence of the alleged bribe.

Coming down hard in the final minutes, Mel? Kind of shady – but then so is paying off a witness.

Our guess: the dentist. You know, the one who had the pictures of her knocked out teeth and such.

Could you just imagine the 180 the case would take if HE was the guy she paid off???
