"American Idol" Redneck? Blake's Alter-Ego Exposed!

TMZ uncovered classic video of "American Idol" beat-boxer Blake Lewis on YouTube -- with buck teeth and a nasty black wig!

On a previous episode of the talent cavalcade, Lewis alluded to his white trash alter-ego "Jimmie Walker Blue." This new video shows Blake in full-on hick disguise, walking through the Summer Meltdown Music Festival in his home state of Washington.
