Mel Gibson has been going through quite a lot of hell for the past weeks. He recently got a formal visit from the Los Angeles County Department of Children and Family Services after his Russian ex-girlfriend Oksana Grigorieva said that he hit her 12-year-old son and lashed out on their eight-month-old daughter.

"The meeting lasted for several hours," a source told RadarOnline.

Gibson allegedly punched Grigorieva in the head during a violent row while she was holding the baby, leaving the tot with a mark on her chin.

She claims that "Mel punched her in the mouth and then again in the side of the head. Oksana has told authorities it was horrific and she thought she was going to die."

"Oksana's doctor diagnosed her with a concussion. It was a result of the punches to her face," according to a source close to the investigation.

"She stayed in bed for weeks following the incident because she was suffering from bad headaches and was dizzy."
