The drummer has worked with some of the biggest names in showbusiness and claims no one has been meaner to him than Sharon, who fired him from Ozzy Osbourne's band.

He's not kind about her in his autobiography, Stick It!: My Life of Sex, Drums and Rock 'n' Roll, and insists fans deserve to know what Mrs. Osbourne is really like.

"She's the most vicious woman in the business," he tells WENN. "She was not very nice to me and I don't know very many musicians who have nice things to say about her."

Appice claims he went out of his way to help Ozzy "fix" the drum sound for his Bark At The Moon album, and was hoping to become a regular bandmate for the Black Sabbath star, but Sharon decided he wasn't the man for the job - and dumped him.

"It just wasn't in her plan to have me be successful on her tour," he adds. "When I joined Ozzy's band I wanted to be there for more than six or seven months... I had an associate production credit on the Bark At The Moon album. I spent weeks in New York with Ozzy finishing the record; doing vocals with him in the studio, trying to fix the drum sound.

"I was getting a lot of press because I was doing these master classes every day and I was giving money to UNICEF from those and playing the arena at night with Ozzy... She (Sharon) just didn't like the fact that they would say, 'The Ozzy tour with legendary drummer Carmine Appice'... We would walk into a city and there's big full-page stories about me and the tour and my UNICEF and my history. She just didn't like it."

Asked for a response, Sharon took the high road and told WENN, "I do not know who this person is."
