Sinead O'Connor has vowed to reveal all about her past sexual encounters in a new book.

The singer confirmed in a statement that she will release her memoirs in March 2016.

It is set to reveal the "sexual dirt on everyone [she's] ever slept with".

The book - which is currently untitled - will be published by Penguin Ireland in the UK and Blue Rider Press in the US.

O'Connor added: "I’ve never stopped expressing myself in my music, and now, with a book."

Blue Rider Press added in a statement that the publication will examine the singer's "turbulent upbringing in Ireland; her breakout as an artist with 1987’s 'The Lion' and the Cobra' and her nine subsequent albums; her controversial opinions and actions, as well as her personal and musical struggles and triumphs, through the present day".
