Isla Fisher fans will be given a treat in her new film Keeping Up With the Joneses, in which the actress strips down for her on-screen husband.

In an attempt to seduce her husband, Jeff (Zach Galifianakis), the redhead tosses her robe aside, revealing a sexy naked bustier and all the trimmings.

Isla flaunts her gorgeous curves in a boob-baring corset combined with thigh-high stockings, and Zach is unsurprisingly impressed.

In the movie, Zach and Isla portray the shy suburban couple Jeff and Karen Gaffney, whose lives are flipped upside down by their new neighbors.

The comedians co-star with Jon Hamm and Gal Gadot as Natatlie and Tim Jones, the newest residents of Gaffney’s suburban street.

The scene with Isla’s Karen happens after she is challenged by stunning leggy model Gal in the lingerie boutique.

Karen and Jeff are skeptical of the couple right away, and the ordinary couple finds themselves caught up in a worldwide espionage operation when they discover their new neighbors are actually government spies.

The film follows a suburban couple as they strive to keep their heads above water in the fast-paced world of their secret agent peers.

Isla is married to Sacha Baron Cohen, a prominent British comedian who said earlier this year that his wife had to “make love” to all of his strange characters.

“My wife has had to make love to all my characters,” he admitted.

“The least favourite was Borat for Isla, and the best was Bruno because of his personal hygiene.”

“I showered, shaved, waxed when I was Bruno.”

“Keeping up with the Joneses” will be released in cinemas on October 21.
