He and Adam Devine are in The Aloha State shooting their new flick, Mike and Dave Need Wedding Dates — but you know what they say about all work and no play, right??
Zac took to Twitter to document his adventure with his co-star to a local lake where they stumbled upon a tire swing and just had a grand ol' time — sans shirts.
He posted the steamy snap (above) of him and Adam posing all perfectly, captioning the shot "Aloha," followed by a series of emojis: muscles, a winky face, the whole nine yards.
And is it just us, or is Adam totally holding his own against the High School Musical star?
But for Zac, a simple snapshot won't suffice. He also showed off his super swinging skillz with this slow-motion video (below)!
