#1 Mel and Robyn Gibson
Despite the fact actor Mel Gibson and wife Robyn Gibson separated in 2006 after having seven kids together, Robyn didn’t actually file for divorce until 2009 (after news broke that her estranged husband had fathered a child with then-girlfriend Oksana Grigorieva), and the couple’s divorce wasn’t finalized until December 2011. Since the two, who married in 1980, didn’t have a prenuptial agreement, Robyn was legally entitled to half of what Mel earned during their marriage. Since Mel’s fortune was estimated to be around $850 million, Robyn reportedly walked away with a staggering $450 million, making it the biggest celebrity divorce settlement of all time. Knowing what we know about Mel now, it sounds like she definitely deserved the big bucks for putting up with him for three decades!
