On February 7, 2013, The Hollywood Reporter confirmed that Roberts had been cast to star in a pilot for Fox called Delirium, based on the Lauren Oliver novels.

Roberts co-starred with John Cusack and Evan Peters in the comedy-drama film Adult World, released on April 18, 2013.
Roberts played a recent college graduate who works at an adult bookstore to make ends meet.
She has said that most of her lines were ad-libbed so her reactions in the film were completely genuine.
Her performance was praised by both Andrew O'Hehir of Salon and Stephanie Zacharek of The Village Voice, who praised Roberts' performance as "both breezy and carefully tuned".
In the next month, she guest starred as Amanda Barrington in the animated sitcom Family Guy, in the episode "No Country Club for Old Men".

Roberts played the lead role in Gia Coppola's directorial debut, Palo Alto, based on James Franco's short story collection of the same name.
The film was released on August 29, 2013.
It received generally positive reviews, with particular praise for Roberts' performance.
Tom Shone of The Guardian and Ian Freer of Empire both called her the "standout" of the film, with Freer praising her performance for being "heartbreaking as she suggests longings and anxieties without over-hyping it.
Much like the film itself."
She next appeared in season three of the FX anthology horror series American Horror Story, called American Horror Story: Coven, in a main role from late 2013 through January 2014.
Roberts portrayed a self-involved party girl named Madison Montgomery, who also happens to be a telekinetic witch.
She then portrayed Maggie Esmerelda, a con artist posing as a fortune teller, in American Horror Story: Freak Show.

In 2015, Roberts starred alongside Palo Alto co-star Nat Wolff in Ashby, portraying the supporting role of Eloise.
The film had its world premiere at the Tribeca Film Festival on April 19, and was released on September 25, in a limited release and through video on demand.
Roberts next appeared in the horror film The Blackcoat's Daughter (also known by its original title February) alongside Kiernan Shipka.
Directed by Osgood Perkins, the film premiered at the 2015 Toronto International Film Festival.
Roberts played the lead character Chanel Oberlin on Fox's comedy horror series Scream Queens, alongside Jamie Lee Curtis and Lea Michele.
The series was created by American Horror Story producers Ryan Murphy and Brad Falchuk, with Glee producer Ian Brennan.
