The proposal happened at backstage at Birmingham, England’s Villa Park on Saturday after the final Black Sabbath show.

One of music's wildest frontmen, who once chewed off the head of a bat on stage, Osbourne performed sitting on a black throne, at times appearing to tear up before an adoring crowd which lapped up hits including Crazy Train. "You've got no idea how I feel. Thank you from the bottom of my heart," Osbourne said.

Ozzy Osbourne is saying goodbye to the stage after performing what has been billed as his final show with the original members of Black Sabbath.
