Penguin Random House imprint Blue Rider Press announced Tuesday the Irish singer and musician is working on a memoir that will come out in March 2016. The book is currently untitled.

O'Connor has been married four times and has described herself as three-quarters heterosexual and one-quarter gay. In a statement issued through her publisher she promises to dish "the sexual dirt" on all former partners.

O'Connor is known for such hits as "Nothing Compares 2 U" and for her blunt, confrontational style. She famously tore up a photo of Pope John Paul II during a 1992 appearance on NBC's "Saturday Night Live."
