Sir Elton John has said Ozzy Osbourne was a "huge trailblazer" who "secured his place in the pantheon of rock gods".
He joined Rolling Stones guitarist Ronnie Wood and other famous faces in paying tribute to the Black Sabbath singer after his death on Tuesday. Sir Elton posted on Instagram: "So sad to hear the news of Ozzy Osbourne passing away.
"He was a dear friend and a huge trailblazer who secured his place in the pantheon of rock gods - a true legend. He was also one of the funniest people I've ever met. I will miss him dearly. To Sharon and the family, I send my condolences and love. Elton xx."
Wood joined Osbourne at Black Sabbath's last gig at Villa Park, Birmingham, earlier this month. He posted on X: "I am so very sad to hear of the death of Ozzy Osbourne. What a lovely goodbye concert he had at Back To The Beginning in Birmingham."
Singer Yungblud, who sang Black Sabbath's Changes at the Back To The Beginning farewell concert on July 5, said he was "heartbroken" by the news and called Osbourne "the greatest of all time".
"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," he wrote in a social media post.

"Lemmy and Ozzy were brothers in arms who enjoyed many adventures together, and his loss is seismic. RIP Ozzy, we will always love and celebrate you..."
