Lisa Stelly, who was married to Ozzy Osbourne's son Jack from 2012 to 2019, shared a tribute to the late rocker, calling him 'papa,' on Instagram

Ozzy Osbourne fans have rushed to social media after spotting a sad 'Changes' duet reference in his daughter Kelly Osbourne's emotional tribute.

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 .)

Yungblud—who covered Black Sabbath's "Changes" during Ozzy Osbourne's final show—said he will be playing the 1972 track "every night" for the rest of his life in honor of the late rocker.

Ozzy Osbourne spent some of his last moments surrounded by his family. He recently spent time bonding with his daughter and her son.

Tony Iommi, Black Sabbath guitarist and co-founder, told UK broadcaster ITV that Osbourne was “frustrated” during the band’s farewell concert on July 5. The heavy metal icon died less than three weeks later, on July 22, at age 76.

"He was and will continue to be a rock n roll legend," Cooper said in a statement, hours after Osbourne died on Tuesday.
