‘Pretty Little Liars’ Season 4 Spoilers: Rumer Willis To Guest Star; Who Will She Play?

“Pretty Little Liars” is adding a new face to season 4. Rumer Willis, the daughter of Bruce Willis and Demi Moore, is set to guest star on the hit ABC Family series.

The Hollywood Reporter broke the news that the “Sorority Row” actress would be coming to Rosewood in an episode slated to air in July. Willis will reportedly play Zoe, the organizer of a worldwide charity. Zoe is said to be the type of person who “will change the world and keep her sense of humor at the same time.”

Currently set to appear only in a single episode, Willis could potentially be returning as Zoe later on in the season. Episodes in July she could potentially appear in include “Face Time,” “Gamma Zeta Die,” “Under The Gun,” and “Crash and Burn, Girl!” No other details on Zoe’s plot line have been revealed.

The new season of “Pretty Little Liars” is said to follow Aria, Emily, Hanna and Spencer as they continue their search for the mysterious “A” after surviving a fire. With Mona out of “A’s” good graces, the girls will look to her for answers regarding their secret torturer. Meanwhile Toby will find himself on a newly designed “A” path.

Photos from the premiere episode also reveal that viewers will finally find out what was in Detective Wilden’s trunk. Rumors are circulating about a body being in the trunk after stills from “A is For A-l-i-v-e” show the girls attending a funeral.

Sean Faris of “Never Back Down” will also be joining the series. According to WetPaint.com, Faris will be playing Pennsylvania State Trooper Gabriel Holbrook. Fans will meet the actor in the premiere when he talks to the liars outside the funeral … possibly about the contents of the trunk.

Season four of “Pretty Little Liars” premieres on ABC Family on June 11 at 8 p.m. Are you looking forward to seeing Rumer Willis? Let us know in the comments.
