In Hollywood, couples who make it past the 10-year mark are rare, which makes the news of their splits even more surprising.
Melanie Griffith and Antonio Banderas are the latest couple whose divorce we didn't see coming. After 18 years of marriage, Griffith, 56, filed the paperwork, citing irreconcilable differences. She asked for joint custody for the couple's daughter, Stella, who will turn 18 in September, though she petitioned for primary physical custody. She also asked for spousal support.
A rep for the couple told ABC News, "We have thoughtfully and consensually decided to finalize our almost twenty years marriage in a loving and friendly manner honoring and respecting each other, our family and friends and the beautiful time we have spent together."

Fans were surprised when the never-married couple Susan Sarandon and Tim Robbins split in 2009 after 23 years and two sons together.

"You can't do a meditation on death and stay in a situation that's not authentic," she told AARP magazine in February. "It made me examine where I was in my union and in my life, and to have discussions about making changes." Sarandon is now dating Jonathan Bricklin, with whom she owns SPiN, a pingpong franchise.
