Ozzy Osbourne was also remembered as 'Papa' in emotional tribute from Jack Osbourne's ex-wife Lisa Stelly, who shared that 'the world got Ozzy' but his family got a loving grandfather.

Osbourne was very active on social media leading up to his death, giving fans an inside look at his final performance and news on his future plans.

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.
