The 72-year-old singer and Sharon, 68, have been married since 1982, and she's admitted that they were having "legendary" fights at one point in time.

She shared: "Our fights were, legendary. We would beat the s*** out of each other. It stopped, must be, 20 years ago, but we had a good run."

Sharon also revealed that she's experienced violence in her role as Ozzy's long-time manager.

She said: "I've hit guys in business and it's like ... sorry. That's the way I was brought up. I famously hit a promoter - I kneed him in the crotch and then I head butted him."

Sharon described her late dad as being "notoriously violent", but admits her attitude towards aggressive behaviour has evolved over time.

She explained: "You grow. You grow to a stage where it sickens you. You grow to a stage where it physically makes you sick, but when you're young and, you know, you're fighting the world. It's different."

The celebrity couple - who have kids Jack, 35, Kelly, 36, and Aimee, 38, together - are currently working on a biopic about their "volatile" romance, and Sharon hopes the film will start shooting in 2022.

Sharon told DailyMailTV: "It's a movie about Ozzy's and my life, how we came together in the early days and our volatile relationship. All the fights, all the makeups, all the fights, all the arrests, all the everything. And it's a love story.

"People are going to watch it go, 'This isn’t allowed. They shouldn't behave that way and put it on film'. But [we're] only talking the truth. Some people have volatile relationships and ours was very volatile."
