Sharon, 60, opened up about her 30-year-marriage with the rocker while she was a part of a TV show, reported Daily Mirror.
"I never knew he was using prescription drugs. I knew he was drinking occasionally, but didn't realise the extent. We're dealing with it. We're not getting divorced. However, I am devastated right now," she said.
Sharon said that she would never be able to change her husband.
The talent show judge and talk show host confessed that she was left devastated when Black Sabbath rocker Ozzy relapsed and started to drink and take drugs earlier in the year.
"It's a disease that not only hurts the person who has the disease, but it hurts the family. It hurts people who love you," she added.
