Billionaire filmmaker Steven Spielberg and his first wife Amy Irving allegedly had a prenup -- but it was on a napkin. When they split in 1989, a judge decided the prenup was invalid and awarded Irving $100 million.
He might not have been a billionaire when he split from Heather Mills in 2008, but Paul McCartney certainly wasn't broke either. The pop icon -- who was declared pop music's first billionaire in 2012 -- and his former wife didn't have a prenup, so Mills was awarded $48.6 million in divorce court.
Richard Mellon Scaife, an ultra-conservative newspaper publisher, failed to protect his estimated $1.3 billion fortune with a prenup when he married his second wife, Margaret Scaife, in 2007. The final amount of the divorce settlement has yet to be reported.
Sumner Redstone, majority owner and chairman of National Amusements (parent company to CBS, Viacom and MTV), split from his wife Phyllis after 52 years of marriage in 1999. With no prenup, Phyllis received $100 million in the settlement.
After 17 years of marriage, Michael and Juanita Jordan divorced in 2006. Though the couple signed a post-nuptial agreement one year after their marriage, awarding Juanita one-half of Michael's fortune in the event of a divorce, she ended up with one-third when they split -- a total of $168 million.
