SNL alum Molly Shannon has joined the cast of Glee.

The former Kath & Kim star has been cast in a recurring role on the FOX musical hit, Entertainment Weekly said Wednesday. Shannon will be coming aboard as astronomy teacher and badminton coach Brenda Castle, the arch enemy of McKinely High School cheerleading coach Sue Sylvester — played by Jane Lynch. According to EW, Molly’s character is described as a 45-year-old spitfire, with a taste for booze and pills and an axe to grind with Sue.
“She becomes Sue’s enemy,” says a Glee tattle.
Molly’s first episode will premiere in May.
