These celebrity divorces ran the gamut from amicable to ugly, and infamous to under the radar, but they have one thing in common:
They were not cheap.
(UPDATE: As of January 2019, we likely have a new #1!)
Donald Trump and Ivana Trump
Donald Trump's divorce from Ivana Trump cost the mogul an estimated $25 million. Given that his net worth is between $1 billion and $10 billion depending on which speech you listen to these days ... he got off easy.
Michael Douglas and Diandra Douglas
Diandra Douglas got an estimated $45 million after she split with Michael Douglas in 2000; he went on to marry Catherine Zeta-Jones ... the divorce from whom is sure to be even more costly.
Phil Collins and Orianne Cevey
Phil Collins and Orianne Cevey split up in 2008, costing the Genesis singer and solo artiste a tidy $47 million. Yeah, those royalty checks from his light rock favorites are not small.
Paul McCartney and Heather Mills
Paul McCartney and Heather Mills finalized their divorce in 2008 after a tumultuous split ended their marriage at four years. Mills walked away with over $48 million, a relative bargain for Sir Paul, who is the most famous, most covered (and thus, wealthiest) entertainers to ever live and still sells concert tickets for $300 a pop ... to play stuff from his Wings years even.
James Cameron and Linda Hamilton
Director James Cameron and actress Linda Hamilton settled their divorce in 1999. Cameron had to pay out $50 million. Then he made Avatar though, so he's doing well.
Kelsey Grammer and Camille Grammer
Kelsey Grammer settled with ex-wife Camille for an estimated $60 million after their divorce became one of the most surprisingly ugly on record. Not just because Kelsey Grammer had so much money that he could cut a check for $60 million ... but because for that amount, he couldn't even legally get her to STFU on Bravo. Time to get a new lawyer.
