Johnny Depp made a surprise appearance on stage with Alice Cooper at the O2 Arena in London on Friday, joining the rocker for a tribute to the late Ozzy Osbourne.
Depp, who performs with Cooper in the supergroup Hollywood Vampires, played guitar on a cover of Black Sabbath's 1970 single 'Paranoid' and stayed for Cooper's 'School's Out'.
The performance came after the Osbourne family announced Ozzy's death on Tuesday. A statement said: 'It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning. He was with his family and surrounded by love.'
Osbourne, born John Michael Osbourne in 1948, co-founded Black Sabbath in 1968. The band was inducted into the Rock and Roll Hall of Fame in 2006, and Osbourne received a solo induction last year.
