Even die-hard viewers of American Idol might have a hard time remembering that Adam Lambert didn't win the competition earlier this year. Especially considering Lambert's high-profile persona lately, starting with his sex-filled American Music Awards performance.

But no, the winner of American Idol was, in fact, Kris Allen, who's seemingly the complete opposite of Lambert. There's no denying they're both great singers, but whereas Lambert is brash, theatrical and loves to knock those high notes out of the stadium, Allen is more low-key, folksy and laid back. The fellow contestants were also roommates at the Idol mansion.
