Constantine Maroulis, finalist from season 4 of American Idol, will be joining the cast of The Wedding Singer on Broadway. According to Playbill.com, negotiations are under way for Maroulis to join the musical, although the character has not yet been announced. Maroulis was last seen squinting and pouting on Idol, but seemed to do little after that, except for showing up in the Idol audience (still squinting and pouting). Prior to taking on the Idol competition, Maroulis graduated from the Boston Conservatory of Music, appeared in indie films and off-Broadway shows. His highest profile gig was touring with Rent. While competing on American Idol, it was revealed that he was the lead singer for a hard rock band, but left the band to try his hand at Idol stardom. He will join The Wedding Singer on September 8th.
