Wait, Is That A Nick Jonas Sex Scene In The New GOAT Trailer?

James Franco also joins the party

The youngest JoBro isn't so young anymore. In a new uncensored trailer for his upcoming movie GOAT, fratty Nick Jonas strips down for sexytime while his on-screen baby brother (Ben Schnetzer) pledges Phi Sigma Mu. Things get real raunchy, real fast.

"Hazing runs contrary to our core concepts of brotherhood and is prohibited in all forms," one guy — probably the president or pledge master — reads aloud at the beginning of the clip. You know where this is going.

The next minute is full of boobs and booze, with upperclassmen pushing freshmen (and their alcohol tolerance) to their breaking points. Hazing may not be allowed on paper, but Phi Sigma Mu — plus a cameo from shirtless James Franco — apparently doesn't concern itself with such formalities.

GOAT, in theaters September 23, was inspired by Brad Land's real experience at Clemson University. Now Jonas and Franco will bring his chilling story to life all over again.
