The network announced Friday that the show has added four new stars, rounding out the cast for the first season. Sydney Park (The Walking Dead) joins the series as Caitlin, a smart, driven girl who thrives under pressure. She's the "perfect daughter of two perfect mothers" and has a dream of following her mother's Senatorial path, which means she might be our new Spencer Hastings (Troian Bellisario).
Newcomer Eli Brown will play Dylan, a gifted cellist who grew up feeling judged by his small town and thus now strives to be the best in everything he does. His two great loves are his music and his boyfriend, Andrew. Gossip Girl alum Kelly Rutherford joins the adult side of the cast as Claire Hotchkiss, co-founder of Hotchkiss Industries and Beacon Heights University. She's a wheeler and dealer who knows how to pull strings to make sure she gets what she wants. General Hospital's Hayley Erin has also been cast in an unnamed role. Let the speculation begin!
The cast is only notably missing an actor for Andrew and someone to play resident snobby-hottie Nathan Hotchkiss, so keep an eye out for those announcements soon.
Pretty Little Liars: The Perfectionists is based on the book series by Sara Shepard. The spin-off also features Sasha Pieterse and Janel Parrish who played Alison and Mona in the original series, respectively. Disney's Sofia Carson also joined the cast earlier this year as Ava, a computer coder who wants to be a fashion icon — so basically if Hanna (Ashley Benson) and Caleb (Tyler Blackburn) had a baby.
