Turns out the winner of Mark Burnett's upcoming rock 'n' roll version of American Idol will step in as the lead singer of an "existing, internationally known rock group" that some people have heard of: INXS. The Rock Star champ will succeed former front man Michael Hutchence, who committed suicide in 1997. "After Michael died, we wanted to search the world for a new singer but didn't know how we could effectively do that," says surviving band member Tim Farriss. "By having Mark... embrace the concept, we've now found a fantastic way to make that happen." Rock Star is currently being shopped to the networks.
