As the rock world and fans alike mourn Ozzy Osbourne's death at age 76, some of his peers teamed up to pay tribute.

Johnny Depp made a surprise appearance during Alice Cooper's latest sold-out gig in London, as he joined the rocker for a performance of Black Sabbath's 'Paranoid' during a tribute to Ozzy Osbourne.

Alice Cooper, in the middle of his sold-out performance, paused to honour his long-time friend and fellow rock legend Ozzy Osbourne, who had passed away just days earlier.

Ozzy Osbourne ’s ‘brutally honest’ autobiography is still set for publication following the music legend’s death. The iconic star died on July 22, aged 76, and his upcoming book will explore the ups and downs of his life, including the cheating scandal that almost ended his marriage in 2016.

The sweet tribute, which came from Osbourne's former daughter-in-law, featured many never-before-seen photos of the late rocker.

Kelly Osbourne is remembering her father, Ozzy Osbourne, with an emotional tribute that calls back to a special father-daughter moment. Two days after Ozzy died at age 76, Kelly shared lyrics from the Black Sabbath song "Changes," which she and Ozzy recorded as a duet together in 2003, to her Instagram Stories.
