|Tom Cruise in "Rock of Ages"|
The 'Mission Impossible' actor was nervous about portraying tattooed musician Stacee Jaxx in the movie version of the musical, so sought advice from the 'Livin' on a Prayer' singer - one of the real life rockers his character is based on.
Jon said: "He and I actually went out and he was very intense about 'how do you do this? ' said, 'Relax man, you're Tom Cruise, you can learn how to sing a song, don't worry about it! "Knowing Tom Cruise from afar, everything that he does, he does to 11."
Jon added he is 'curious' to see the results ' which will include Tom taking on his band's hit 'Wanted Dead or Alive' ' but isn't worried the actor will be playing a part which will caricature his own onstage persona. He added to website Extra: "I'm pleased, I'm curious. I don't think that he's gonna be worried about duplicating my things - it'll be an amalgam of stuff. In the meantime, I think it's pretty neat."
