Length Of Marriage: 16 days

If you're the unmistakable bald-headed Sinead O'Connor, you can't exactly set up a profile on Match.com if you're looking for love. Instead, she posted something like a personal ad on her blog, requesting a man and life-partner who was "no younger than 44 ... Must not be named Brian or Nigel ... Must be blind enough to think I’m gorgeous."

Herridge, an addiction counselor for children, seemed to fit the bill, though he was perturbed when Sinead insisted on tracking down some doobage on their wedding night. Sinead also blamed Herridge's "inner circle" for subverting the marriage before the reception had even ended. The couple went on a honeymoon, then lived together for a week before announcing they were calling it quits.
