Sharon Osbourne explains why Ozzy's cheating 'meant nothing' to her until one specific incident

Staying married to a legendary rock star is never easy, especially if your partner is the 'Prince of Darkness' himself, Ozzy Osbourne.

Ozzy's at times rocky relationship with wife and manager Sharon was laid bare for all the world to see on the pioneering reality TV show The Osbournes, where viewers became familiar with the couple's unique dynamic over the show's four seasons.

This dynamic came back into the spotlight in 2017, when Sharon admitted that Ozzy had cheated on her multiple times during their four decades of marriage. Surprisingly though, this infidelity 'meant nothing' to her.

In a tearful interview on Piers Morgan: Uncensored, 73-year-old Sharon spoke about the family's struggle since Ozzy's sudden death in July, while also reflecting on her unconventional life with the Black Sabbath singer.

"I know it’s a whole thing with a lot of women, "If you go with somebody else, that’s it. It’s over." But we’re all so different. It didn’t faze me," she admitted.

The former America's Got Talent judge explained that her perspective comes from her difficult upbringing and the world she knew as a young woman that was filled with "addicts and alcoholics and people like that, it was the 70s. It honestly didn't faze me at all".

She even revealed details about some of the six women that her husband had been cheating with, who she described as 'some Russian teenager, then a masseuse in England, our masseuse out here, and then our cook.'

Sharon has also said of the cheating: "He had women in different countries. Basically, if you’re a woman giving Ozzy either a back rub or a trolley of food, God help you"

But while Sharon was able to compartmentalize Ozzy's wandering eye, her even-handedness soon faded when the aging rocker tried to carry on his unfaithfulness at home

"A couple of times, it was like, 'I don’t like the fact you brought them to my house.' And it is my f*ing house. I would go to him, 'I furnished it!' That I didn’t like," Sharon told Piers Morgan.

This issue that came to a head in 2016 when Ozzy was forced to apologize publicly for carrying on a four-year affair with the celebrity stylist Michelle Pugh, 20 years his junior.

Ozzy claimed that their relationship had been purely physical, saying in a statement that he was 'sorry if Ms Pugh took their sexual relationship out of context.'

His spokesperson later apologized 'to the other women he has been having sexual relationships with.'

Sharon, who married the star in 1982 and shares three children with him, said at the time: "When I found out about the hairdresser, I couldn’t believe it. Because none of these women were show ponies; he was doing it to fill the void in some way."

The aging musician would go on to admit that he had a sex addiction, while Sharon would speak candidly as a co-host of CBS' the talk about his randiness.

Speaking on a panel about sex in 2018, Sharon shared: "This is a bone of contention in our house... because he’s got a problem. He’s just like a rabbit."

In sharp contrast to the brain-damaged heavy metal pioneer, Sharon found herself winding down in later life.

"I am like, birthdays, Christmas," she told viewers. "At this point in my life, it’s special occasions. it's thanksgiving - why not?"
