Mel Gibson was quite contrite in an e-mail to his ex, Oksana Grigorieva, written the morning after he allegedly hit Oksana twice, knocking out some of her teeth.

“Could you please call me. I want to tell you how unspeakably sorry I am,” Mel wrote in an e-mail now in the hands of the authorities, reports Radar.

That same morning, in a separate e-mail, Mel wrote, “How’s your tooth?”

There was some question as to the validity of a photo taken of Oksana with her front teeth knocked out just days after the alleged fight, but if this e-mail is found to be authentic, it definitely strengthens Oksana's claims!

The two have been locked in a bitter custody fight that has now expanded to claims of abuse on his part and extortion on hers.
