Sinead O'Connor has said she is looking forward to "dishing the sexual dirt on everyone I've ever slept with" in her autobiography after she signed a book deal.
The Irish singer, who has been married four times, will discuss her upbringing and music career in the book, which is set for publication by Penguin in 2016.
She said: "I've never stopped expressing myself in my music, and now, with a book. And I look forward to dishing the sexual dirt on everyone I've ever slept with."
Penguin said the book would also cover "her controversial opinions and actions, as well as her personal and musical struggles and triumphs".
Michael McLoughlin, managing director of Penguin Ireland, said: "We are delighted to be publishing Sinead's memoirs. She is one of the most distinctive cultural figures of our time and she always has something interesting to say. We believe there will be enormous interest in this book."
Sinead parted from her fourth husband in 2011 after just 16 days of marriage.
The singer, who had a worldwide hit with her cover of Prince's Nothing Compares 2 U, has regularly found herself at the centre of controversy, including tearing up a picture of the pope on US TV in 1992.
At one point she was ordained as a priest and on another occasion she declared she was gay - shortly before marrying for the second time in 2001.
