Tom Cruise has made it official. No, not that. The Rock Of Ages casting thing. He's now officially signed on to shake his ass for Adam Shankman in the Hollywood adaptation of the Broadway hit.

The first name to sign on, Cruise will play rock god and Arsenal front man Stacee Jaxx. His big number in the film will be Bon Jovi's "Wanted Dead Or Alive." I can't say speak to his singing ability but I've always enjoyed Cruise in his villain roles. So to see him play the sneering, egotistical rock star should be fun. At the very least, he's sure to have ridiculous 80's hair. And screen-grabs of that will make my job fun for at least six more months. (THR)
