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.

Ozzy Osbourne uploaded what would become his last Instagram post on July 21 — just one day before he died. The photo was taken at Osbourne's farewell show in Birmingham, which took place just weeks earlier.

Morrison — who played guitar in Idol’s band — noted that his “thoughts and [his] love” are with Ozzy’s wife, Sharon Osbourne, and their kids, Jack, Kelly and Aimee. (Ozzy was also the father of Elliot, Louis and Jessica, whom he shared with ex-wife Thelma Riley .)
