Zac Efron was spotted on the set of his new movie Dirty Grandpa wearing nothing but nude-colored briefs.
In the film, Zac plays Jason Kelly, an uptight groom about to be married, who is tricked by his perverted former army general grandfather (played by Robert DedNiro) to drive to Florida for Spring Break.
They’re currently filming in Georgia’s Tybee Island.
That’s really all we know about the movie at this point, but thanks to these photos we’ll be in the theater on opening night!
