Another day, another shirtless picture of Zac Efron. But who are we to complain, eh? This time, we get to glimpse his triumphant physique in a brand new trailer for Bad Neighbors 2 and like Dirty Grandpa and the upcoming Baywatch the new flick promises to whip us thirsty gays into a frenzy with oodles of glimpses of buff bod. And as you’ll see, not only does our Zac serve good six pack, he also throws some great shapes. Just check out those pelvic thrusts! Swoon!
