The 53-year-old was paranoid she wasn't good looking enough to grace the former Black Sabbath rocker's arm, and longed to be lusted after.
Sharon - who has spent $5.4 million (GBP3 million) on a series of cosmetic enhancements - says, "I was never a good looking woman. Guys would say I was great to hang out with and great fun, but none of them ever wanted to f**k me.
"(After the surgery) I feel more sexually attractive for him (Ozzy). I guess more like the kind of person he should have on his arm. People used to think I was his mother. I would go f**king insane. It really p**sed me off."
