Feelin' fratty, Zac Efron?

The sexy star was spotted on the set of his new flick Townies, where he was snapped taking a break from filming as his bulging biceps stood out in a tight white T-shirt.

The 25-year-old hunk was looking very frat-tastic in a fraternity tee and matching tattoo while rocking tight jeans and a belt with a marijuana leaf buckle. 

Efron put on his best frat boy front as he strolled around set, looking like the picture-perfect (and superhot!) pledge who would make even the craziest sorority girl swoon. 

Directed by Nicholas Stoller and also starring Seth Rogen, the upcoming comedy follows a frat boy whose behavior affects a local neighbor's family life, and we can't wait to see Efron's college antics play out on the silver screen.

From an innocent High School Musical star to a troublemaking college dude, we'll take Zac naughty or nice any day. Stay hot.
