Sharon said on her US TV show: "I've never discussed it out of embarrassment. I was 27 and I was just going out with Ozzy at the time. When we first got together we'd drink a lot. We had a session of partying and it's about four in the morning. He says to me, 'How much do you really love me?' And I'm saying, 'I'd do anything for you. Anything, I absolutely adore you. I'd give my life for you.'

"I'm like, 'I'd die for you.' I went to a room service table and there was a steak knife. I get the knife and I'm like, 'I love you so much' - and slash, slash, slash on my wrist."
