"New Girl" actor Max Greenfield has signed on to FX's "American Horror Story: Hotel."

"This October, Max Greenfield (like you've never seen him) is checking in to the hotel … but not checking out," co-creator Ryan Murphy teased in a tweet.

The fifth season of the hit anthology series boasts a cast that includes Lady Gaga, Matt Bomer, Angela Bassett, Evan Peters, Sarah Paulson, Kathy Bates, Chloe Sevigny, Wes Bentley and Cheyenne Jackson.

No details have been revealed about any of the characters or the storyline. Heck, the only thing we know about the new installment is that it's (presumably) set in a hotel.

"American Horror Story: Hotel" premieres in October on FX. Greenfield will also return in January for the fifth season of Fox's "New Girl."
