Sinead O'Connor's reason for ending her 16 day marriage is a doozy. [View all]

Must have been great weed.

(PEOPLE.com) -- Sixteen days after her December 8 Las Vegas wedding to boyfriend Barry Herridge, Sinead O'Connor is ending the marriage, the "Nothing Compares 2 U" singer announced Monday on her website.

"Dear friends," O'Connor 45, writes, "I had for reasons u will all understand, wished to keep this private but have been told today it is to be leaked in the next few days despite my best efforts. So I must now leak it myself so as the record is straight."

She blames pressures placed upon him by "certain people in his life" not to be with her based on press reports about her.

"Within 3 hours of the ceremony being over the marriage was kyboshed by the behaviour of certain people in my husband's life. And also by 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," she writes. "My husband was enormously wounded and very badly effected by that experience and also by the attitude of those close to him toward our marriage. It became apparent to me that if he were to stay with me he would be losing too much to bear."

She adds, "A woman wants to be a joy to her husband. So.. U love someone? Set them free."
