Mel Gibson's Wife of 28 Years Files for Divorce

After nearly three decades, Robyn Gibson blames "irreconcilable differences" for split from Oscar-winning hubby

The passion of the wife has run dry.

Mel Gibson's wife of 28 years, Robyn Gibson, filed for divorce from the Oscar-winning director-actor, citing the ever-popular "irreconcilable differences."

"Throughout our marriage and separation we have always strived to maintain the privacy and integrity of our family and will continue to do so," the estranged couple said in a joint statement issued through their publicist, Alan Nierob.

While the divorce petition doesn't specify when the duo separated, the Gibsons have  reportedly been living apart for some time.

They married in June 1980 and have seven children together, though only one—son Tom, who turns 10 tomorrow—is a minor. Robyn is seeking joint physical and legal custody of the boy, as well as spousal support.

Gibson's net worth has been estimated at upwards of $900 million.
