Until now ... maybe.
Earlier this morning, Radar Online posted a photo of Oksana taken hours after she claims Gibson punched her in the face during a January 6 altercation.
The image is part of the L.A. County Sheriff’s Department's ongoing investigation of the deeply troubled actor, who may face domestic violence charges.
It’s also being used by Oksana in her custody battle with Mel over their eight-month-old daughter Lucia. You can see the awful photo for yourself here.
The question is: Did Mel Gibson do it?
Not necessarily. Oksana says he punched her twice in the mouth, knocking out her teeth and giving her a concussion. But is the pic consistent with that claim?
According to TMZ, Oksana's teeth were not damaged, despite her dentist submitting in a declaration that one veneer was knocked out and another damaged.
Experts who have analyzed the photos believe that Grigorieva's injury is inconsistent with being punched in the mouth since there is no soft tissue damage.
In other words, it may have been self-inflicted and this is a shakedown.
There is "no evidence of external or internal damage," a law enforcement source told the celebrity gossip site. Mel has denied physically attacking Oksana.
Gibson's lawyers are expected to accuse Oksana of trying to extort Mel out of more than $10 million in return for keeping the tapes of his tirades private.
As for the rant in which Mel apparently admits beating Oksana, telling her she deserved it after she referenced him punching her, that's questionable too.
Mel's legal team wants taped rants thrown out as evidence because of "strong evidence" they were edited and tampered with ... it's all extremely weird.
Basically, the Gibson tapes are what they are - in terms of vulgarity, and proving in chilling detail that one of Hollywood's biggest stars needs serious help.
But there's also so much we don't know: Why he is SO angry? Were the recordings altered? Is her injury really self-inflicted? Will either face charges?
That we'll have to wait and see. (thehollywoodgossip)
