The FX anthology series American Horror Story has built a reputation for having one of the strongest casts on television, which makes the first major addition to season five most intriguing.

Producers Ryan Murphy and Brad Falchuk have tapped Grammy-winning musician Lady Gaga to star in the fifth season, which is apparently titled American Horror Story: Hotel. We're thinking a haunted hotel, perhaps following different visitors in different eras? Just our two cents. After the casting news broke, Gaga posted a short teaser (the first for season five) that seemingly revealed the new subtitle.

As for what the subtitle actually means? There's no official indication, though the addition of Gaga in a major role comes as a coup for the series and could be indicative of even bigger cast shakeups for the latest season. Longtime standout Jessica Lange has previously indicated she may reduce her participation in future seasons of the anthology, while each run has typically remixed some existing cast members, such as Sarah Paulson and Evan Peters.

Though Gaga might be one of the biggest and most unorthodox stars to join the series (this will mark her official acting debut), the anthology has previously featured a star-studded list of actors, such as Kathy Bates, Zachary Quinto, Dylan McDermott, Joseph Fiennes, Michael Chiklis, Kate Mara, Adam Levine, Lance Reddick, Neil Patrick Harris and a ton of others.

Check out the first teaser below and let us know what you think:

American Horror Story: Hotel is tentatively set to debut this October on FX.
