Sinead O'Connor abruptly ended her marriage to her fourth husband Barry Herridge ... after just 16 days.
The couple wed on December 8 -- the Irish singer's 45th birthday.
The news was announced on Sinead's website. "He is a wonderful man. I love him very much. I'm sorry I'm not a more regular woman," she posted. "I truly believe though it is painful to admit, we made a mistake rushing into getting married, for altruistic reasons, and weren't aware or prepared for the consequences on my husband's life and the lives of those close to him. He has been terribly unhappy and I have therefore ended the marriage. I think he is too nice to do so. And too nice to trap."
Still, Sinead had nothing but well wishes for her younger beau. "We part amicably. I wish him to be free and happy and loved and supported and for him to have privacy as that is utmost important for his job and for the children he treats as a therapist so I plead on theirs and his behalf for media to please leave him and his family alone. I really beg this."
The couple wed at the Little White Wedding Chapel in Las Vegas -- the same place Britney Spears married her first husband Jason Alexander. Their marriage was annulled just 55 hours later. Click on the "Launch gallery" button above to see more of the shortest marriages ever above!
