Mel Gibson: Oksana Grigorieva Injured Herself!

Mel Gibson's latest defense against allegations that he battered his now-ex, Oksana Grigorieva? That the crazy chick actually did that to herself. Seriously.
Oksana claims Mel scratched and bruised her January 6, which he denies, admitting only that he slapped her once, not hard, to protect their daughter.
As for how she appeared injured in photos taken after the fact?

SOMETHING'S FISHY: Mel says it's Oksana's story.

Mady Shany, Oksana's facialist, says in a declaration to the court that on January 12, Grigorieva came in for a facial, and she noted, "I noticed there were scratches and bruises around her eyes and on her forehead."
Shany says Oksana told her Mel "punched her and threw her on the bed while she had the baby in her arms." But was she lying about the abuse?
In Mel's declaration, he says Oksana is unstable and "suffers from Trichotillomania, an impulse control disorder characterized by the repeated urge to pull, and pulling, out ones own hair, eyelashes, eyebrows and other body hair."
