Johnny Depp Honors Ozzy Osbourne at Alice Cooper Concert

Johnny Depp made a surprise appearance at an Alice Cooper concert at London's O2 Arena, honoring Ozzy Osbourne. The appearance came just days after Osbourne's death.

Depp played guitar on the song “Paranoid,” with Cooper on vocals wearing a t-shirt with Osbourne's face. They also played a mashup of “School’s Out” and “Another Brick in the Wall Part 2.”

The appearance marked a reunion for Depp and Cooper, who have previously collaborated in the Hollywood Vampires.

The Hollywood Vampires band was named after the 1970s rocker clique created by Cooper, Ringo Starr, Keith Moon, Micky Dolenz, and Harry Nilsson.
