Singer married Barry Herridge, a therapist from Dublin, in a drive-through ceremony in Las Vegas on 8 December
Sinead O'Connor has announced that she is separating from her fourth husband, less than three weeks after marrying him in a drive-through ceremony in Las Vegas.
The Irish singer said that she and Barry Herridge, a therapist from Dublin, were parting amicably but claimed that the marriage was "kyboshed by the behaviour of certain people in my husband's life" within three hours of the wedding.
She also blamed "a bit of a wild ride I took us on looking for a bit of a smoke of weed for me wedding night as I don't drink".
"My husband was enormously wounded and very badly affected by that experience and also by the attitude of those close to him toward our marriage," she wrote in a blog post on her website.
"It became apparent to me that if he were to stay with me he would be losing too much to bear."
Herridge, 38, and O'Connor, 45, were married on 8 December in a chapel in Las Vegas after she said on Twitter that she was seeking a boyfriend.
In the Boxing Day post on her website, she said that they had "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," she said.
O'Connor, who said that she and Herridge had lived together until Christmas Eve, made a plea to the media to leave Herridge and his family alone, saying that while she was "fair game", he or his family were not.
She said she intends "to get on with being fully me", adding: "I am a 21st century full woman and proud of living it."
"I am in a very good and happy and strong place in life so I am doing fine."
She added that she and Herridge "haven't been awful to each other. So while I feel sad for my husband, and sad to be the cause of sorrow to yet another poor man, I'm also happy that I know we weren't horrible to each other and he is better off free. And that I can be me. And that's a freedom I can't give up for anyone or anything. Neither should my husband or anyone else."
O'Connor has been married three times in the past. Her first marriage was to the music producer, John Reynolds, while her second husband was a journalist. Her third marriage took place in 2010, to the Australian musician Steve Cooney.
