Who Is The Biggest "Idol" Star?

For a long time, the answer was clearly Kelly Clarkson, the only "Idol" winner to become a hit worldwide. Then Carrie Underwood released a smash-hit debut that places her alongside Clarkson, Jennifer Hudson made an Oscar worthy film debut and suddenly we've got ourselves a race. But let's not forget Will Young. The FIRST winner of "Pop Idol," Young hasn't broken out in the US, but he was the first to prove an "Idol" winner could have a real career. He's delivered three hit albums, appeared in the modest hit film "Mrs. Henderson Presents" and came out without any fuss. Now he's making his stage debut in the Noel Coward play "The Vortex." Clearly, he's in it for the long haul.
