UPDATE: Head over to Round 2 of our bracket to cast your vote!
The past year has seen some shocking celebrity divorces, with couples old and new parting ways amid storms of mutual accusations and legal filings. Not every split came as a surprise, but each one made it that much harder to believe that true love really does last forever.
While the United States divorce rate has reached nearly 50 percent, the celebrity set is even less lucky in love. According to the International Business Times, a 2010 study of Golden Globe winners determined that the chances of a marriage surviving in Hollywood is only 35 percent, with the odds at 1.9 to 1 against the union -- quite the deterrent for the Demi Moores and Kim Kardashians out there.
