From Mrs. Doubtfire to Good Will Hunting, Robin Williams has always been my favorite actor.

He was known for having a heart of gold and bringing laughter to all of Hollywood. The comedian also went above and beyond for those less fortunate, spreading kindness wherever he went.

This made the news of his tragic passing at only 63 even harder, but for those who loved him, his legacy lives on.

One of these people is Sharon Osbourne, 65, whose daughter Kelly, 33, recently revealed Williams came to her mother's aid when she was battling colon cancer back in 2002.

Kelly, said her mother began to give up hope over her prognosis, and considered stopping treatment when she began losing her hair.

"It was not a very fun time at all for anyone. Probably the least amount of fun for Mom," Sharon's 32-year-old son Jack shared on the family's inaugural podcast episode.  

"Mom had got to a point in her chemotherapy that she'd kind of given up, because it was when Mom's hair started to fall out," Kelly said. "Mom was lying in this bedroom that she had curtained off. It was pitch black -- she hadn't gotten out of bed for like a week."

"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," she added.

Luckily, it wouldn't be long until Ozzy came up with a surefire way to raise his wife's spirits.

With the help from Williams, the family was able to tear Sharon away from her depressive state.

"Dad said laughter is the best medicine and organized for Robin [Williams] to come over and make mom laugh, and he just dropped everything and came over to the house and got in bed with Mom," Kelly revealed.

"I just remember sitting at the bottom of the stairs and we went from crying, not knowing what to do, to just peeing ourselves laughing because we could hear Mom upstairs in her room laughing with Robin. And, the next day it changed everything and Mom went back to chemo," she added.

During the show, Sharon couldn't say enough great things about her late friend, who was "one of the nicest, genuine people that you could ever meet."
