SINÉAD O'Connor has announced her sobriety on Facebook after 30 years of being a "weed head."
The Nothing Compares to You singer made the revelation yesterday morning on her social media page.
In a string of posts, O'Connor announced she had had surgery for an unknown reason, and had hormone replacement therapy.
She also revealed she is now residing in a suburb of the San Francisco bay area, San Rafael.
After having a short hiatus earlier this year from social media, the singer explained to her fans she was in rehab.
On her Facebook page she said, "I was in rehab by the way. For thirty years of being a weed head."
She also said she will be living in a "sober living environment."
"Can proudly state I now have clean piss and will be in a 'sober living environment' for the next year," she said.
"It's more like a home environment. Only its complete with support system. Which is a first for me.
"Proud of self. Wasn't easy. 0-18 years in Ireland and then 34 years in music business and the shit that's gone on for the last year.... it's a miracle I wasn't on every drug in sundry. #CleanP*ssRocks."
Alarms were raised earlier this year when O'Connor was reported missing by Chicago Police when she did not return from a bike ride on May 15.
After her return, the singer penned a furious post to family members. The strongly-worded letter addressed her four children and her financial troubles.
