No. 4. Scotty McCreery
Birthdate: Oct. 9, 1993 (age 17)
Why He's Hot: When viewers first saw Scotty McCreery at the Milwaukee auditions for "American Idol" season 10, they could barely believe the big ole voice coming out of the North Carolina teen. McCreery skated through the season not only on his baritone and Josh Turner covers, but also his fresh-faced charm and country drawl. Crowned "Idol" champ back in May 2011, McCreery signed to Mercury Nashville shortly and delivered his first smash single, "I Love You This Big," to radio shortly thereafter. McCreery's idol status is set to loom even larger when his anticipated debut album, "Clear as Day," is released on Oct. 4.
