C'mon, admit it. Dorky, funny guys turn you on! This comedic cutie from Connecticut is hilarious onscreen (next up he'll be playing a chipmunk in Alvin And The Chipmunks). And his wit carries over into real-life, too! You'll melt over Justin's sarcastic sense of humor, and -- bonus! -- he's super-smart, too: he graduated from Vassar, and his dad is a professor. Nice!
