Oksana Grigorieva turned down $15M settlement from Mel Gibson

Oksana Grigorieva turned down a $15 million settlement offer from ex-lover Mel Gibson because he wanted shared custody of their daughter.

The Russian singer — who is currently involved in a bitter custody battle with Mel for their 11-month-old daughter Lucia — refused the huge financial offer because she didn’t want the “unstable” actor getting so much access to their child.

“The $15 million was a proposal that I walked away from because he wanted 50 per cent custody of an infant when he’s unstable,” she told People magazine.

Oksana — who split from the Edge of Darkness star earlier this year amid allegations he assaulted her during their relationship — also claims Mel punched her in the head while she was holding Lucia, during an argument on January 6.

“Mel ran in and started screaming all kinds of nasty words. Then he just hit me twice with his fist. Boom, boom, to my head and my mouth,” she said.

“I fell on top of the bed. I’m just covering the baby and not protecting myself. He proceeds to choke me with both his hands.”

The 40-year-old beauty alleges the 54-year-old actor used a mixture of threats and pleading to convince her not to leave him after the incident.

“The worst thing for Mel is public humiliation,” she said. “He threatened to kill me if I went to the police.

“You can’t just cut off love when you’re a victim of domestic violence. He was begging for another chance the following day. On his knees. He apologized for hitting me. He said he will never, ever touch me again.”

However, Oksana admitted the beginning of her relationship with the 54-year-old actor was very different, with Mel claiming he wanted to spend the rest of his life with her.

“He wrote letters professing to be so in love with me,”she said.

“In 2008, he gave me a Claddagh ring — a type of Irish wedding ring. He professed his commitment for the rest of his life.”
