Zac Efron Goes Nearly Nude in Tight Briefs, Plus See His Crop Top!

Helloooooo, Zac Efron—and hello, Zac Efron’s butt!

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!

On the second day (and we must start there because it’s a sight to behold), Efron was snapped running around in a tight pair of nude briefs—and nothing else. “Team Hornet” was written across his 8-pack abs, sand covered his body, and a small stuffed hornet was held just so to cover his, er, particulars.

Thank You!

But April 27’s outfit is not to be ignored, either. The High School Musical alum rocked a black crop top with ’90s-style fringe on each sleeve and around the stomach. Gloriously, it read “Hakuna Matata” in a script that morphed into an infinity symbol. (#YoloForever.) He teamed the shirt with yellow and white-striped pants, splattered with blood.

But don’t be alarmed! The blood was fake, just used in a scene for the wild film, in which an ex-army grandpa (played by Robert De Niro) convinces a nervous groom to go on a boys-gone-wild trip with him. The comedy is slated to hit theaters Dec. 25, 2015.
