Financial terms of the divorce were not disclosed. Mel Gibson’s fortune, which has at least three houses in the posh resort of Malibu (West Los Angeles), is estimated at $ 900 million.
Robyn Gibson – who officially returned to Friday’s maiden name, Robyn Denise Moore – had filed for divorce in April 2009, on the basis of “irreconcilable differences” with her famous husband, aged 55.
The couple, who married in 1980, had seven children – six boys and one girl.
Mel Gibson is also the father of a girl of 26 months, he had with his former girlfriend Oksana Grigorieva.
The actor, who won two Oscars for “Braveheart” in 1996 (Best Picture and Best Director), hit the headlines repeatedly in recent years.
In early 2011, he had made a deal with prosecutors to avoid prison in a case of alleged domestic violence against Oksana Grigorieva, scooping three years of probation.
In 2006 he was arrested driving his car with a blood alcohol one and a half times the legal limit, and sentenced to three years probation and fined $ 1,300, after taking rehab.
His arrest was coupled with a scandal, the actor who uttered on this occasion several anti-Semitic insults, for which he had later apologized.
