Aubrey Plaza is about to get dirty…

The 30-year-old half-Puerto Rican actress/comedian has joined the cast of Lionsgate’s road trip comedy Dirty Grandpa.

The Parks and Recreation star will star opposite Zac Efron and Robert De Niro in the film about an uptight twenty-something (Efron) who embarks on a road trip before his wedding to bond with his recently widowed grandfather (De Niro) only to find that his grandpa is a foul-mouthed lunatic on a mission to get laid during Spring Break.

Plaza will portray Lenore, a savvy, beguiling party girl looking for fun on Spring Break.

Dan Mazer (Da Ali G Show) is directing from a screenplay by John Phillips.

Lionsgate has already slated the film for an August 12, 2016 release.

Plaza returns to NBC television this month for the seventh and final season of Parks and Recreation. Her film credits include Safety Not Guaranteed, The To Do List, Scott Pilgrim vs. The World, Funny People, and Damsels In Distress.

She next appears in Hal Hartley’s Ned Rifle and in A Driftless Area with John Hawkes. She also stars with Natasha Lyonne and Judy Greer in Jamie Babbit’s indie comedy Fresno.
