The 27-year-old actor filmed his new movie, Dirty Grandpa, on April 27 and 28, and on both days, he rocked very daring ensembles—one of which put his pert booty on display!

Also starring Robert DeNiro and Julianne Hough, the comedy centers around an uptight guy who is tricked into driving his grandfather to Florida for Spring Break. The film is due out August 2016.

Zac Efron we love your butt so much!
