Mel Gibson has completed his court-ordered anger management course.

The 'Mad Max' star was sentenced in March 2011 to three years' probation - including a 12-month domestic violence counselling programme - over an alleged attack on ex-girlfriend Oksana Grigorieva.

According to TMZ.com, the 56-year-old Oscar winner's lawyer told Los Angeles judge Stephanie Sautner yesterday (02.03.12) that in addition to completing the required course hours, Mel has also undergone extra therapy sessions.

Although the actor was not present, the report claims the father-of-eight - who also had to carry out 16 hours of community service after pleading no-contest to the misdemeanour battery charge - will be officially released from probation if he stays out of trouble for the next two years.

The case began when Oksana alleged he hit her with a closed fist and broke a veneer on her tooth during a row in January 2010. Mel admitted to slapping her but said he did it because she was "shaking and tossing" their then-baby daughter Lucia around whilst arguing. He maintains that he did not punch her.

The 'Braveheart' director was previously married to Robyn Moore for 26-years before they separated in 2006.
