While it's probably more common than not for celebrities to legally protect their money before walking down the aisle, many say "I don't" when it comes to prenups. Sometimes it's because they got married well before fame and fortune came to call, sometimes it's because they simply find such paperwork distasteful, and other times ... well, let's just say their hearts got in the way.
Guy Ritchie & Madonna
After eight years together, Madge and the film director split in 2008. He was worth $45 million so he wasn't exactly poor, but she was worth closer to $500 million. And while he initially said he didn't want any of her money, thanks, he took a $92 million parting gift anyway.
Paul McCartney & Nancy Shevell
Paul clearly doesn't believe in prenups. Even after his second marriage (to model Heather Mills) ended in a nasty and very expensive divorce in 2008, McCartney -- who's reportedly worth some $800 million -- once again eschewed legal asset protection when he wed businesswoman Nancy Shevell in 2011. (The good news for Paul? Nancy has money of her own.)
Russell Brand & Katy Perry
The celebrity couple tied the knot in 2010, and while the marriage lasted barely a year, Brand could've laid claim to tens of millions of dollars -- half of what his superstar wife made during that time period. But apparently he took a pass, and both of them left the marriage with their original assets intact.
Kelsey & Camille Grammer
At the time of his 1997 marriage to Camille, Kelsey was only four years into an incredibly lucrative 11-year run on 'Frasier.' After the couple broke up in 2010, he asked a court to declare those first four years his separate property. It took another two years to hammer out a settlement, and while it was confidential, sources say Camille walked away with at least $30 million.
Mel & Robin Gibson
In 1980, Mel -- then a struggling actor -- married wife Robyn. Thirty years and seven children later, she filed for divorce, and when the dust settled in 2012, she was a single woman worth roughly $425 million. To date, it's the most expensive celebrity split in Hollywood history.
Ryan Phillippe & Reese Witherspoon
When Reese and Ryan married in 1999, they were both up-and-coming actors. They split seven years later, and by then, she was a huge star making $20 million a movie (compared to his respectable but much smaller $3 million/movie). Even still, he didn't ask for spousal support -- only shared custody of their two kids.
Nick Lachey & Jessica Simpson
Lachey's boy band 98 Degrees was super hot when he wed Simpson in 2002, but by the time they divorced three years later, she was the one making most of the money -- by some estimates, she'd earned upwards of $36 million during the marriage. He reportedly didn't get half, but he did get a lot more than the $1.5 million she initially offered.
Ashton Kutcher & Demi Moore
The May-December couple tied the knot in 2005 and split six years later when Kutcher was caught in a nasty cheating scandal. In the interim, he became television's highest-paid actor -- and their lawyers are still hammering out how much of that money will wind up in Moore's possession.
Tom Arnold & Roseanne
Before their 1990 wedding, Roseanne was so head-over-heels for Tom that she reportedly fired her attorney for even suggesting a prenup. Turns out she should've listened -- four years later, Arnold walked away with a $50 million divorce settlement. Things were contentious between them for almost two decades, but they decided to let bygones be bygones after Tom took part in her Comedy Central roast in 2012.
Ellen DeGeneres & Portia de Rossi
Together since 2004, the adorable couple legally wed four years later. The popular talk show host brought a lot more money into the marriage than her actress wife -- but it was Ellen who didn't want a prenup, supposedly saying she finds them "unromantic."
