Did Mel Gibson Knock Oksana Grigorieva’s Teeth Out?

This just in: Mel Gibson is a few sandwiches short of a picnic. But did the kooky Oscar winner knock his Russian baby mama’s teeth out?

Last week, Gibson filed a restraining order against his ex girlfriend, Russian singer Oksana Grigorieva, but he Octomom doppleganger claims she already had a restraining order against OctoMel after he punched her, knocking out her two front teeth in a vicious spat.

Three months after the pair split, Mel, 54, is taking legal action against his 40-year-old ex and challenging the custody arrangement with their 7-month-old daughter Lucia, according to PEOPLE Magazine. Mel has accused Oksana of being abusive towards their daughter during an argument in January, before they abruptly split.

“Oksana was completely out of control that day, screaming, and shaking Lucia like a rag doll,” a source squealed to the mag. “Mel stepped in to stop her from injuring the baby.”

Oksana, on the other hand, claims that during the same argument Mel punched her and knocked out her two front teeth. She spilled the beans on her troubled relationship and nasty custody spat with Gibson in an exclusive chat with London’s Sunday Mail.

Grigorieva brands her former flame “cruel,” accusing him of failing to provide child support their little girl.

“He is not paying me a penny. Nothing,” Grigorieva told the paper. “There are so many lies being said about me. I was trying to keep things dignified and be respectful to the father of my daughter, but what he is doing is cruelty. I am having to live on credit cards and borrowed money. It is not a good situation,” she continued.

“We were together for three years. So much that is being put out there is wrong. He didn’t dump me, I left him. I rescued my children and myself. There is no restraining order against me, but my lawyers went to court and a judge granted a restraining order against him.”
