Johnny Depp made a surprise appearance alongside Alice Cooper to pay tribute to Ozzy Osbourne at a concert on Friday night, days after the rock icon's death.

Alice Cooper didn’t let the passing of Ozzy Osbourne go unrecognized. During a sold-out concert at London’s O2 Arena on July 25, Cooper, donning an Osbourne T-shirt, led a powerful tribute to the late rock legend just days after his death was announced.

Ozzy Osbourne, who died July 22 at the age of 76, was known as the singer of influential heavy metal band Black Sabbath and for his outrageous solo career that earned him the title the Prince of Darkness. Yet Ozzy also had a softer side. He was a huge fan of the Beatles.
