54-year-old Mel Gibson has had a busy year. In the past 12 or so months he’s gotten divorced from his wife of 19 years and mother of seven of his children Robyn Moore, had his eighth baby with his Russian girlfriend Oksana Girgorieva, and broke up with Oksana.

Oksana, who had aspirations of  a singing career when Gibson went public with her last year, recently filed a restraining order against Gibson, and now TMZ reports he got so violent with her this January that he actually broke some of her teeth and gave her a concussion!

A source told TMZ: “She tried to protect his reputation, depsite 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.”

Her attorney’s issued a statement claiming that all the details will “come out in a court of law.” Watch out, Mel!
