Charisma Carpenter, alumna of cult series classics Buffy The Vampire Slayer and Veronica Mars, has been cast in Ryan Murphy’s comedy-horror Fox anthology series Scream Queens. The show’s star, Emma Roberts, let it slip on Instagram today that the comedy will premiere on the first Tuesday of the season, September 22. In a guest starring/potential recurring role, Carpenter will play the mom of another lead on the show, Ariana Grande.

In the first season of Scream Queens, a college campus is rocked by a series of murders. The series, which Murphy created with fellow Glee co-creators Brad Falchuk and Ian Brennan, hails from 20th TV and Ryan Murphy Television. Lea Michele, Jamie Lee Curtis, Oliver Hudson and Abigail Breslin co-star.

Carpenter, who also co-starred on The Lying Game, is repped by TalentWorks and manager Gladys Gonzalez.
