"Glee" alum Darren Criss is booking a room at "American Horror Story: Hotel."

According to E! News, he's tying up a deal to play Justin, a hipster who checks in with his girlfriend on Halloween in hopes of escaping trick-or-treaters, only to run afoul of hotel head Kathy Bates with too many room-service demands.

Criss' character will be introduced in the Halloween episode of the FX series, and then returning in a recurring role.

He joins a sprawling cast that also includes Lady Gaga, Matt Bomer, Evan Peters, Sarah Paulson, Denis O’Hare, Finn Wittrock, Lily Rabe, Chloe Sevigny, Wes Bentley, Naomi Campbell, Cheyenne Jackson and Max Greenfield.

“American Horror Story: Hotel” premieres in October on FX.
