Splash NewsThe Townies set just got a bit steamier.
After showing off his biceps in a tight fraternity tee in one scene, Zac Efron put the moves on Halston Sage in another, pulling the 19-year-old blonde beauty close for one serious smooch.
During the frat-party scene, Efron, 25, sports a military jacket and totes a sword, while his on-screen ladylove rocks short white shorts and a black hat.
It's clear he's wasted no time getting back into the swing of things following his hand-breaking incident during a fight scene with costar Dave Franco.
In the upcoming comedy, Efron stars as a frat boy who disrupts the quiet suburban life of a family man (Seth Rogen) who lives near his frat house.
Rose Byrne and Lisa Kudrow also star in the flick, set to hit theaters in 2014.
