In the Osbourne family’s inaugural podcast, they shared their highs and lows from their eponymous reality show and touched on Sharon’s health battle.

“It was not a very fun time at all for anyone. Probably the least amount of fun for Mom,” Jack Osbourne shared.

Daughter Kelly Obsourne chimed in that Sharon, now 65, had started to give up during her chemo treatments after her hair began to fall out.

“Mom was lying in this bedroom that she had curtained off. It was pitch black,” Kelly, 33, recalled of the troubling time. “She hadn’t gotten out of bed for like a week. Mom’s dog had to go to the hospital because she was dehydrated. Mom was dehydrated. And we couldn’t get her to go back to finish the chemo.”

Then Ozzy Osbourne had the bright idea to bring in Williams to cheer up Sharon.

“Dad said laughter is the best medicine,” Kelly remembered. “And organized for Robin to come over and make Mom laugh. And he just dropped everything. Came over to the house. Got in bed with Mom. I just remember sitting at the bottom of the stairs and we went from crying, not knowing what to do, to peeing ourselves laughing because we could hear Mom upstairs in her room laughing with Robin. The next day it changed everything and Mom went back to chemo.”

Sharon couldn’t share enough great things about Williams and his good deed during her illness, calling him “one of the nicest genuine people that you could ever meet.”

Williams committed suicide in August 2014 after a battle with Lewy body dementia that had gone undiagnosed prior to his death. He was 63.
