THE first trailer for Dirty Grandpa has landed, and it looks as wild as we predicted.

The upcoming comedy sees Zac Efron and on-screen grandfather Robert De Niro take a road trip shortly after the death of his wife, and the pair descend on spring break.

Bikini babes, beer pong, drunken hook-ups and drugs, nothing is off limits for Dick’s (De Niro) last hurrah, while grandson Jason (Efron) reluctantly acts as his wingman.

Dick even hooks up with a college student (played by Aubrey Plaza) in one NSFW scene.

Dirty Grandpa, which is a follow-up to director Dan Mazer’s 2013 rom-com I Give It A Year, also stars Julianne Hough as Jason’s uptight fiance, Meredith.

Dirty Grandpa hits US cinemas January 22, 2016. An Australian release is yet to be announced.
