The former X Factor judge, 63, spoke candidly with broadcaster Jeremy Paxman - who was diagnosed with Parkinson’s himself 18 months ago - in his ITV documentary Paxman: Putting Up With Parkinson's, which aired on ITV on Tuesday.
The former University Challenge presenter asked Sharon whether it is harder for those looking after someone with Parkinson’s, than actually having the disease - something she disagreed with.
“I just think of my husband, and like you, who was very energetic, loved to go out for walks, did a two-hour show on stage every night, running around like a crazy man,” she reflected emotionally.
“Suddenly, your life just stops - life as you knew it.”
“When I look at my husband, my heart breaks for him, I’m sad for myself to see him that way, but what he goes through is worse. When I look at him and he doesn’t know, I’m like crying,” Sharon - who shares three children with Ozzy continued.
Paxman was also curious to know if there were any positives about the disease, to which she replied: “The positive thing is we spend much more time together as a family and I love my husband more than I do three years ago.”
Sharon and Ozzy celebrated their 40th wedding anniversary this year.
While their union has been infamously stormy in the past, they seem stronger than ever after he was diagnosed with Parkinson’s in 2019.
Appearing on ITV’s Lorraine in June, she said: “I love him more now than ever, I respect him. I do.”
When asked about her declaration by show host Lorraine Kelly, Osbourne elaborated: “Because we all change, constantly, constantly evolving and he has evolved into a really great guy; he’s a good guy.”
