Gaga, 28, also revealed season 5's title. "Hotel," she whispers in her Twitter video as she takes off her sequin mask.
This past month, FX Networks CEO John Landgraf told TVLine that AHS viewers should expect the upcoming season to be "very different" from what they've seen in the past. "One of the things I love so much about that is that it can be radically, radically reinvented in terms of tone, setting, period, characters, cast," he said. "I think there's going to be an unusually large reinvention in between Book 4 and Book 5 relative to, say, between Book 3 [Coven] and 4 [Freak Show].
For those that watch Murphy's other show Glee, it's no secret that he's a fan of the outlandish pop star. In the singing show's first season, he directed and wrote an episode dedicated to Gaga's music, titled "Theatricality," and the FOX series also did a Katy Perry vs. Lady Gaga dramedy episode in season 5.
The "Born This Way" singer's AHS
role will be her first major TV role following bit parts in feature films Sin City: A Dame to Kill For
and Machete Kills.
As AHS fans might recall, Murphy recruited another musician for American Horror Story: Asylum, Maroon 5 frontman Adam Levine.
