Constantine Maroulis

Brooklyn-born Constantine Maroulis pissed off his regular vomit-metal band for a shot at the 2005 American Idol title, only to be whipped by a redneck and a Barbie-doll crooner. Quite a dis for a dude who can tackle “Bohemian Rhapsody,” Hedwig and Rent. Maroulis graduated to star in Rock of Ages on Broadway, while finding time to record his overproduced 2007 pop debut.
