Sinead O'Connor memoir with "sexual dirt" due in 2016

Sinead O'Connor has a book deal, and she's not writing for kids.

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."

In recent years, though, she's made more headlines because of her dating life.

In August, she released a new album called "I'm Not Bossy, I'm the Boss."
