Can he ever not act creepy?

Mel Gibson -- worth north of $900 million -- is probably cheating on his wife. He has no prenup. Ouch. From the National Enquirer:

Mel Gibson is facing Hollywood's most costly divorce ever - a vicious battle over his whopping $900 million fortune. Shocking new photographs of the rough-and-tumble Oscar winner with a sexy young Russian singer could be the final straw for the actor's long-suffering wife Robyn, sources told the Enquirer. The exotic beauty -- a leggy 28-year-old brunette named Oksana -- was first spotted with Gibson, 52, in September. She popped up again on the set of his latest movie a few weeks later -- and for Robyn, it will be the final nail in the couple's turbulent 28-year-marriage, insiders say.

"Robyn's had enough," a close family friend tells the Enquirer, "She's been to hell and back with Mel over the years. The drinking, the cheating, the temper tantrums. The last time Robyn took him back she told him, 'This is your last chance. If you ever embarrass me again, we're done.' And now she intends to keep her word. Robyn is finished with him. It's about respect now. Mel was spotted going into his trailer three days in a row with this girl in September. Tongues were wagging that it was a full-fledged affair." (Print Edition - 12/1)

If there were ever a wife that deserved half of her husband's fortune, it's Robyn. Not only has she put up with Mel's drinking, womanizing, and accent all these years, but after seven kids, her vag has to be almost as gaping as Paris Hilton's. For Mel's sake, hopefully that craigslist ad he posted yesterday pays off and he finds himself a good lawyer:
