THR reports that Willis will join Season 4 of PLL as Zoe, a charity organizer. She’ll appear in one episode for sure with the potential to appear in more. Zoe is the type of girl “who will change the world and keep her sen of humor at the same time.”
Rumer’s episode will air in late July, making it probably the seventh or eighth episode of the season.
The 24-year-old actress previously recurred on “90210” as Gia Mannetti. Her other credits include “Hostage,” “The House Bunny,” “Sorority Row” and an episode of “Hawaii Five-0.”
“Pretty Little Liars” returns to ABC Family on Tuesday, June 11 at 8 p.m. ET/PT.
