Oksana Grigorieva: 'Mel Gibson couldn't get aroused unless he beat me'

Mel Gibson has already admitted to hitting his ex-girlfriend Oksana Grigorieva last year while she was holding their child, and as if that wasn't bad enough she's now made an explosive accusation against him while under oath in court.

She claims the only way Mel could become aroused was by getting violent, and that he regularly beat her during sex.

Sources at Oksana's deposition relayed her claims to TMZ. This is the first time she's made this allegation against her ex and in previous statements to police she had only ever mentioned that one violent incident.

Well, we didn't think Mel Gibson could become any more vile, but there you go.
