Mel Gibson about to break major bread..........for life . You know the old saying - it's cheaper to keep her .

The Associated Press........Mel Gibson is not only single, but $425 million poorer, thanks to a divorce settlement finalized Friday between the actor and his wife of 31 years, Robyn Denise Moore.

The judgment, finalized by a judge in Los Angeles, keeps virtually all details of the settlement secret. People magazine reports that the couple did not have a prenuptial agreement, meaning his ex-wife would be entitled to half of everything Gibson earned during their marriage.

The Oscar-winner’s fortune has been estimated to be as high as $850 million, the magazine said, citing a 2006 report in the Los Angeles Business Journal.

Throughout the 31-year marriage, which produced seven children, Gibson directed, invested and starred in movies such as “The Passion of the Christ,” which grossed more than $600 million alone. He also invested heavily in real estate, including an island in Fiji he bought for $15 million in 2005.

People also reports that Moore, a former dental nurse, is entitled to half of any film residuals Gibson receives for the rest of his life.
