It was announced back in February that Gaga would be "starring" in the fifth season of the show, continuing Murphy's trend of looking to the music world to flesh out his casts. He recruited Fleetwood Mac's Stevie Nicks to portray herself - albeit as a witch - while also calling on Ariana Grande and Nick Jonas to appear in his new Fox series Scream Queens. A whole batch of A-listers from Britney Spears to Gwyneth Paltrow appeared on Glee.

Greenfield and Gaga will join returning stars Kathy Bates, 66, and Sarah Paulson, 40, on American Horror Story, as well as newbies Cheyenne Jackson, 39, Wes Bentley, 36, and Matt Bomer, 37, who previously appeared on Freak Show.

Jessica Lange - who will not be returning to the show - seemingly dismissed the casting of Gaga in particular, saying, "What does that mean? ...I don't understand the question," when asked whether the pop superstar had managed to convince her to stay for another season.
