Oh no, not another nanny scandal!
Sharon said she hired the caretakers while her three children were young because she traveled so much that she needed assistance.
However, it didn't end up the way she envisioned it because the woman would apparently get into bed with her rockstar husband.
"We used to have four nannies because I had three children. I would work five days a week, I would travel," she said.
"You can't work a nanny seven days a week, so we had four nannies employed rotating. And I'm telling you they were the bane of my existence. They were all wanting to be celebrities."
She continued, "They were all wanting money. I caught two of them in bed with Ozzy different times. And it goes on and on and on."
Sharon didn't specify what exactly happened or when the flings took place, but it's believed they occurred in the late 80s or early 90s when the couple's children were younger and at the age when nannies are typically used.
Of course, Sharon stayed with the Black Sabbath frontman despite the possible infidelity. In fact, she defends her man saying she was wasn't of sound mind and was on drugs and alcohol.
Because of his mental state, she even said she wasn't angry with him.
She said, "He was out of his mind. He's calling me his first wife, he's calling them me, he don't know!"
That isn't to say that she wanted the behavior to continue. Sharon combated the nanny situation by hiring a male nanny.
Over the course of their 33-year marriage, the couple has remained loyal, despite a short, temporary split in 2013 when Sharon found out Ozzy was using again.
They got back together shortly after, when Ozzy vowed to stay clean.
"She was very pissed off," Ozzy said of his wife at the time. "I thought I was gonna lose my family at one point."
