Jen on her 'Justin-Approved' Stripper Ensemble

By
Jennifer Aniston, Jason Sudeikis, Emma Roberts and Will Poulter play a faux family that assembles for the ultimate road trip -- to smuggle drugs across the border -- in the hilarious comedy We're the Millers, and Jen is perfectly game to share details with ET about her racy strip-tease moment in the movie -- and how she modeled her various lingerie options for fiance Justin Theroux!
"It was fun to model that all, be enjoyed," quips Jen of her stripper ensemble that Justin "approved."
Watch the video as Jen and Jason also share a laugh and crack a few jokes about the intense interest in their respective upcoming weddings to Olivia Wilde and Justin -- and their "relay race" to see who gets hitched first!
In theaters August 7, the new comedy from Dodgeball director Rawson Marshall Thurber finds Sudeikis as a small-time tasked with moving a huge shipment of weed into the U.S. from Mexico for an insanely wealthy client (played by Ed Helms). Believing that all-American families get through the border unnoticed by authorities, he recruits his neighbors to pose as the "perfect family" – a cynical stripper (Aniston), a virgin "dork" (Poulter) and a runaway "gutterpunk." Can they hold it together long enough to pull it off?
