AGE: 25

YOU'VE SEEN HIM … As the rhythm-challenged yokel Willard in last year's Footloose remake; at the party of the century in this month's Project X.

UP NEXT: Playing a party animal about to wreck his best friend's med-school chances in 21 and Over (directed by the writers of The Hangover).

THE COMIC STYLINGS OF: "The makers of 21 and Over have been screening it, and I'm getting a lot of comparisons to a young Vince Vaughn. I think it's the delivery: He's a fast talker, and we both ad-lib a lot, and Vince has that quality of … he can be an asshole. You're just like, 'How are you saying these things and getting away with it?'"

SOUTHERN COMFORTS: "Going to high school in rural Florida, we always partied down in the woods. Somebody—one of the rednecks­—would leave class and mow a path out to a field, and we'd drive out there. Dude, every party I went to was lit by a bonfire. Acoustic guitar. Cooler full of beer."

Next stars: Max Thieriot, Diego Boneta, and Tom Payne.
