"He said he's been using alcohol and prescription drugs for the last year and a half," she said of his recent Facebook post about getting sober. "And that he's been an a–– and he's been in a very dark place. That's true. That's very true."
The Talk co-host also revealed on Tuesday's show that Ozzy was hiding his struggles from her. "I never knew he was using prescription drugs," she said. "I knew he was drinking occasionally but I didn't realize the extent."
And like her husband, who said on Facebook that the couple are not splitting up, Sharon said, "We're not getting divorced. However, am I happy? No. Am I upset? Yes I am. I'm devastated right now."
Speaking generally about addiction, Osbourne told her costars and her audience about the toll it can have on a family when someone is abusing substances like alcohol and drugs.
"It's a disease that not only hurts the person that has the disease but it hurts the family. It hurts people who love you," she said. "We're dealing with it. We've dealt with worse. We're dealing with it and this too shall pass."
In true Osbourne style, she couldn't miss the chance to end on a humorous note: "Otherwise," she added, "my husband will be taken to hospital to get my foot removed from his ass."
