10 Stars Definitely Appearing In American Horror Story: Hotel

10. Lady Gaga

Previous Seasons: None

While it might seem fairly obvious that the producers of American Horror Story wouldn't cast a famous musician if they didn't have some sort of musical arc to the new season, it may not be as black and white as that. Gaga is known for her theatrical background and according to sources, she's a rather convincing actress in her own right.

Fans still wonder though, is Gaga going to play some sort of musician or is she going to go a totally different route? There are some theories going around that she will play a "beautiful and strange heiress", but only time will tell for sure.
