This North Carolina native and former American Idol contestant was so good that even though he placed fourth during his season, he landed a recording contract with RCA right away. His band’s debut album sold more than one million copies within five weeks of release. In fact, it was the fastest selling rock album debut in Nielsen Soundscan history!
 
Long before he was on TV's hottest singing reality show, this guy played in a high school band and later sang vocals for several rock bands in Burlington, NC. Prior to Idol, he auditioned for the CBS talent reality show Rock Star: INXS but failed to make it on the show.
 
This sexy hunk ranks below only Carrie Underwood and Kelly Clarkson in album sales of former American Idol alumni, and he didn't even win! After Idol, he's gone on to partner up with huge artists like Slash, Lifehouse, Timbaland, and Carlos Santana.

After watching him all covered up on American Idol during his season, this rocker's newly-chiseled bod definitely had us doing a double-take to recognize him at all when this picture surfaced. So which Idol alum is this? Click through the photos below to find out! (And sorry ladies... but he's already taken!)
