Sinead O'Connor memoir with 'sexual dirt'

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

Penguin Random House imprint Blue Rider Press announced on 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, 46, has been married four times and has described herself as three-quarters heterosexual and one-quarter gay. In a statement issued through her publisher the singer promises to dish "the sexual dirt" on all former partners.

The Nothing Compares 2 U hitmaker is known 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.

Last year, O'Connor was embroiled in a feud with Miley Cyrus after she penned an open letter slamming the young pop star.

O'Connor accussed Cyrus of being "pimped" by the music and labelled the performer "anti-female".
