Earlier this week, Lea Michele raved about various guest stars set to join Glee in the fall.

With that in mind, Sarah Drew should be flattered.

The young actress - who has appeared on Mad Men and Castle, among other hit show - has landed the role of Suzy Pepper, an unstable senior that develops an obsessively creepy crush on her teacher.

Drew is booked for one episode, but there’s potential for this to be a recurring role.
