American Horror Story Hotel
American Horror Story Hotel will feature Lady Gaga as an evil CountessFX

American Horror Story: Hotel is one place you would not want to check-in this October, but you sure will be tempted to do so! And in season 5 of the FX series, fans would see singing sensation Lady Gaga, playing an evil Countess, who consumes blood of victims to maintain her youthful looks.

Creator Ryan Murphy in an interview with Entertainment Weekly has revealed that Gaga is willing to do anything on the horror anthology series, and she has even filmed a foursome sex scene with Matt Bomer.

Murphy admitted that Gaga was the only actress he has worked with and admitted that she "wanted to do more explicit stuff than was written".

"You write a foursome for her and you expect a lot of questions. She never did that. She showed up and she was wearing diamond pasties, a Band-Aid on her hoo-ha, heels, and a black veil that Alexander McQueen made for her on the day before his death. Then the crew gasped in delight and we were off!"

Lady Gaga who is making her American Horror Story debut as an enigmatic figure named the Countess, alongside Matt Bomer -- who is playing her paramour Donovan -- filmed a scene which involves the Countess and Donovan having "naked fun with another male-female duo in her hotel penthouse".

Speaking about Gaga's character, Murphy said, "There's nothing scarier than a platinum blonde baby running around doing evil deeds."

According to FX, The Hotel mentioned in the show is named The Hotel Cortez, which was built by mass murderer James March (Evan Peters). This diabolical businessman chose Room 64 at the Cortez for his office. In modern day, that room is not a place guests should venture in, although many unfortunately do.

1. Teasers: Murphy unveiled three creepy American Horror Story: Hotel teasers with each video about 15 second in length.

One of the recurring images in this season of AHS is a number of sewn together into mattresses in rooms at the Hotel Cortez, which can be seen in the video.

Two other promos show a brood of young, blonde bloodsuckers and a glimpse of room no 64 when there is a knock on the door.

2. Disturbing scenes: Murphy recently announced that this year's instalment would feature "the most disturbing scene we've ever done" and it involves New Girl star Max Greenfield, Sarah Paulson's Sally and a little fella named The Addiction Demon.

Greenfield plays Gabriel, a platinum blonde junkie who checks into the Cortez in the premiere and has a run-in with both Sally and Demon.

Greenfield teased, "Ryan gets real pleasure out of how far, I think, he can push it. And when we were doing that stuff, he was happy and he was scared. We all were. And it was a good vibe on set because of that. I think we were like, 'F— yeah, man. Let's push this and let's see how far we can go."
