Married: 6 hours
What Went Wrong: This classic doomed romance perhaps started the trend of fast-paced divorce. Valentino, a famous Italian actor — nicknamed "the Latin Lover" — impulsively married the American actress in 1919. She quickly regretted the decision and locked him out of their honeymoon suite. After knocking for 20 minutes (the door, not boots), he headed home. In divorce proceedings, she claimed they never consummated their union.
Married: 2 days
What Went Wrong: The pop star wed her childhood sweetheart in a quickie Las Vegas ceremony in January 2004. Approximately 55 hours later, the marriage was annulled. She has since referred to their union — for which she allegedly proposed — as a "joke that went too far." Funny!
