Mel Gibson’s wife, Robyn Moore, has filed for divorce after 28 years of marriage citing “irreconcilable differences.”

Gibson and Moore met in the late 1970s soon after filming “Mad Max.”  Robyn was a dental nurse and Mel was an unknown actor.  The couple married in June of 1980 and according to TMZ there is no prenuptial agreement.  Under California law, community property, including a fortune which was estimated at $900 million in 2006, is divided 50/50.

The Gibson’s have one daughter and six sons, however, only one — Tom, who turns 10 tomorrow, is a minor.

Robyn filed the divorce papers on April 9th.  She is seeking joint physical and legal custody of Tom, spousal support and attorney’s fees.  Her attorney is Laura Wasser, who represented Britney Spears in her split from Kevin Federline.
