Sinead O'Connor and Prince "detest each other", despite collaborating on one of the most successful songs of her career.
Sinead's career took off when she covered the little known track 'Nothing Compares 2 U' by the US musician, but when they actually met up in person, they didn't get on at all.
She told Uncut magazine: "I loved his music, but I had absolutely no idea or expectation that that single would be such a big hit, not at all. Did I ever meet Prince? I did and... We didn't like each other. At all. Ha ha! I'm not going to go into it, but we detest each other.
"It got violent too, which is why I can't go into it, but it is a very funny story. I'll tell it when I'm an old lady and I write my book."
Sinead's version of 'Nothing Compares 2 U' went to number one in 14 countries in 1990, kickstarting her career, helped by its emotional video. Sinead has previously said music was her saviour in life.
She said: "I would definitely be dead if not for music. I prayed very fervently as a small child that God would give me a way out.
"And I remember distinctly walking home down this laneway, I can't have been more than five or six, and with the rhythm of my feet I began to hear music, and within that second I made the association with the Holy Spirit, and I said thanks to it.
"I felt it was the answer to the prayers. I get to stand there and scream and I have a right to, 'cause what else am I gonna do?"
