While Adam Lambert didn't make his sexuality a major talking point while competing on "American Idol" -- he later came out in a "Rolling Stone" cover story -- "Idol" viewers and fans at home knew there was something special about the flamboyant contestant. Lambert was out in his personal and professional life well before he hit the "Idol" stage and made his mark as the contestant to watch. On the show, he fired up audiences with his glam rock stylings, sexed-up stage persona and multi-octave range. Though he finished the 2009 season of "Idol" in second place, he remianed the season's breakout star. His major label debut album "For Your Entertainment" has sold more than 800,000 copies in the U.S. and earned him a Grammy Award nomination for the No. 10 Hot 100 hit "Whataya Want From Me." -- Keith Caulfield
