Just days before Ozzy Osbourne’s passing, Kelly Osbourne — who costarred on the MTV reality series "The Osbournes" with her dad as well as mom Sharon Osbourne, 72, and brother Jack Osbourne, 39, from 2002 to 2005 — addressed online speculation that the heavy metal icon’s health was deteriorating.

Ozzy Osbourne was the greatest singer heavy metal ever knew, his voice a keening wail that seemed to float above the heaviest of riffs, from his earliest days of laying the foundation for what metal would eventually become at the helm of Black Sabbath to a solo career that somehow held its own against the weight of his own legacy.
