Mel Gibson's divorce has been finalized and ex-wife Robyn did very well in the end. She walked away with roughly $425 million since the couple didn't have a prenup.

The two were married for 31 years and have seven children together. Mel is worth about $850 million, which means Robyn gets half of his earnings. Robyn is also entitled to half of any film residuals Gibson receives for the rest of his life. This is probably the biggest celebrity divorce payout in Hollywood history.
