“It has a voice like my dad’s David Attenborough or something. And it starts out saying, ‘I don’t need a doctor to tell me that I’m going to die. I know I’m going to die,’” the reality TV star said on her Instagram Stories.

“What the f–k is wrong with you people? Why would you spend your time making a video like this?” Kelly said, insisting that Ozzy was “not dying.”

“Yes, he has Parkinson’s, and yes, his mobility is completely different than it used to be, but he’s not dying,” she said.

The “Fashion Police” alum also addressed the alleged suicide pact between her parents after Sharon’s past comments on the matter.

“Stop making articles or posts about how you think my parents are having a suicide pact,” she said. “That was bulls–t my mom said to get attention one time. And my dad’s not dying. Stop.”

Sharon discussed the alleged pact on an October 2023 episode of “The Osbournes Podcast,” divulging that she and Ozzy had made a plan to go to Switzerland and use the services of physician-assisted suicide organization Dignitas.

At the time, the “Talk” alum said she preferred not to “suffer,” adding, “I don’t want it to actually hurt.”

“Mental suffering is enough pain without physical,” she said. “So if you’ve got mental and physical, see ya.”
