Mel Gibson's Russian ex-girlfriend and baby mama Oksana Grigorieva has made some serious claims against him. She said that he punched her and knocked some of her teeth out.

A source from Gibson's camp told TMZ that she was making false accusations and that he was never "violent" with her, although things got a little physical during an argument on January 6. However, Oksana says, "Mel and his camp are spinning the facts in a desperate attempt to protect his reputation."

It has been a battle of he-said, she-said. Gibson says that she shocked their baby during an argument, whereas Oksana said that she was just trying to protect their daughter.

"She tried to protect the baby during one of Gibson's violent episodes when he punched Oksana in the face two times, breaking her teeth and giving her a concussion," a source said.

"She tried to protect his reputation, despite her fears of him and his verbal and physical abuse.

"She regrets having believed in his empty promises to obtain professional help to control his violent nature."

Oksana filed a restraining order against Gibson earlier this week prohibiting him from coming within 100 yards of her.
