Zac Efron's Shirtless 8-Pack Is on Full Display as He Shamelessly Adjusts His Package on 'Neighbors 2' Set

Well, with a body like this why would Zac Efron ever wear a shirt?
The 27-year-old Neighbors actor was snapped on the Atlanta, Georgia set of the highly anticipated sequel, Neighbors 2: Sorority Rising, where he wasn't shy about going shirtless and sporting nothing but a pair of bright orange booty shorts.
And he clearly had no shame adjusting his package out in the open either.

Judging by these killer dance moves, Zac's obviously continuing his frat boy antics from the first film in the scene -- despite, SPOILER ALERT, having supposedly moved on to being a shirtless greeter for Abercrombie & Fitch at the end of Neighbors.

… But who really cares when he's flashing his 8-pack abs.

The thirst from the hundreds of extras is almost palpable, no?

Zac's co-star, 33-year-old Seth Rogen, gamely tried to keep up, rocking an identical outfit and also sporting a "six-pack."

Earlier this month, Selena Gomez was spotted hilariously posing as a sorority girl on the Atlanta set of the star-studded comedy. Selena joins Chloe Moretz in the sequel, as well as returning stars Zac, Seth, Dave Franco, and Rose Byrne, who appears to be rocking a real-life baby bump on set! This would be the first child for Rose and her boyfriend, actor Bobby Cannavale, who have been dating since 2012.
Watch the video below to see a baby-faced Selena do her best impression of a sorority girl, sporting a hot pink tube dress.
