Osbourne’s own band was among the first to recognise the rock star’s passing, heading to social media to commemorate their most famous member with a single photo.
“Ozzy Forever,” they wrote.
Mike McCready, the lead guitarist and founding member of American rock band Pearl Jam, reflected on the “sad” news of Osbourne’s death over X.
“When I was in high school I discovered Sabbath. War Pigs was terrifying and mesmerizing at the same time," McCready wrote.
“It was Ozzy’s voice that took me away to a dark universe. A great escape. Then when the Blizzard of Ozz record came out I was instantly a fan.
“Randy Rhoads was an influence on me to play lead guitar. Luckily I got to play on the song Immortal on the last record.
Dominic Richard Harrison, who goes by the stage name Yungblud, said the rocker was “full of life” when he performed with Osbourne weeks ago at his final Black Sabbath concert in Birmingham.
“I didn’t think you would leave so soon the last time we met you were so full of life and your laugh filled up the room,” the 27-year-old shared on X.
“But as it is written with legends, they seem to know things that we don’t. I will never forget you - you will be in every single note I sing and with me every single time I walk on stage.
“Your cross around my neck is the most precious thing I own. You asked me once if there was anything you could do for me and as I said then and as I will say now for all of us the music was enough.
“You took us on your adventure - an adventure that started it all. I am truly heartbroken. You were the greatest of all time.”
