Kaiser’s take on the story:

Was it the drinking, or the other women? Was it the not-so-alleged anti-Semitism, or Mel Gibson’s habit of referring to women as “sugart-ts”? In any case, after 28 years of marriage, Mel Gibson’s wife has had enough. Robyn has filed for divorce in California. The papers were filed last week, and she is seeking legal custody of their one minor son. They have six other adult children.

Sources are claiming that they do not have a pre-nuptial agreement, and that most likely their assets – more than $900 million – will be split close to 50/50. Mel’s only comments are from his representative, who says “Throughout our marriage and separation we have always strived to maintain the privacy and integrity of our family and will continue to do so.”

Mel Gibson’s wife Robyn has filed for divorce after 28 years of marriage.
In the papers — signed Apr. 9 — she cites “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,” a rep for Gibson, 53, tells Usmagazine.com in a statement.

TMZ alleges that “there is no prenuptial agreement” based on source reporting. In 2006, Gibson’s fortune was estimated at $900 million. Under California law, community property — which includes earnings — is divided 50/50.

Robyn — who famously stood by Gibson during his highly publicized 2006 DUI arrest — lists the date of separation as “to be determined,” which TMZ points out is important because “earnings generally cease to be community property when the couple separates.”

Robyn, who has seven children with Gibson, has requested spousal support and attorneys’ fees. She is also seeking joint physical and legal custody of their son, Tom, who turns 10 Tuesday. (Tom is their only child who is a minor.)

Robyn has snapped up attorney Laura Wasser, who most recently represented Britney Spears in her split from Kevin Federline.

The couple have dogged split rumors for some time.

Gibson was recently photographed with a woman who did not appear to be his wife in Costa Rica on March 4.

Asked at the time if he and Robyn had split, his rep had no comment.

“Mel is on family vacation with his entire family and their friends,” a source told Usmagazine.com. “His sons are there with their girlfriends, his pregnant daughter is there – the whole family is there.”

What was it about this last affair that bothered Robyn so much? Mel’s always had a reputation as a womanizer, he’s just been more obvious and disrespectful about it in recent years. That, plus the alcoholism – that’s why I think Robyn had enough. Is it bad that I really hope Robyn takes him to the cleaners? She deserves a $450 million-plus settlement. Perhaps she’ll threaten to do a tell-all if Mel doesn’t pay up? She must know all of his secrets – the real dirt, that he really doesn’t want to get out.

MSat’s take on the story:

The tabloids have seen this one coming for months. Though Robyn cites “irreconcilable differences,” it’s more like “alcohol abuse/cheating/egomania.”

I say, it’s about time. I’m sure the $900 million was incentive for Robyn to stay with Mel through the years, in spite of his alcohol problems, but all bets were off when the photos of Mel’s mistress made the rounds. I suppose there was no way for Mel to deny it, or for Robyn to look the other way once those photos came out. I would agree that Robyn deserves some spousal support for sticking it out for 28 years with a man who probably was no picnic – even when his career was at its peak. And if this mistress thinks for a second she’s going to change his ways – good luck with that!
