Lady Gaga's first regular TV gig is the stuff of nightmares, according the spoilers from "American Horror Story: Hotel" creator Ryan Murphy.

"She'll give you nightmares," he told E! News. "When you see her you will say 'Holy s-t.'"

Gwyneth Paltrow's boyfriend Brad Falchuk, the showrunner of "AHS," added, "She will terrify you and you will also be in love with her at the same. She's Gaga."

Lady Gaga will play Elizabeth who owns the hotel where the events will take place.

"She is sort of a very wealthy social doyenne who is consumed with art and fashion and people and she has a nefarious plan that is revealed in the first episode and plays out over the course of the season," the director said.

According to "American Horror Story: Hotel" spoilers from E! News, Lady Gaga's The Countess will also engage in some sex scenes with both the male and female guests of the hotel.

While Lady Gaga's character is very deviant, her real personality is very far removed from The Countess.

"I've met and worked with a lot of great people, legends, on and on and on," Ryan Murphy recounted. "She was somebody I was very intimidated by and I thought, 'Oh, Lady Gaga. The mystery, the mystique.' I really thought there was a [Greta] Garbo element to her of elusiveness and mystery."

He continued, "What I have found is she is just the best, most fun, most joyful person. Like, you would be stunned. She is so funny and she is down to Earth, and she comes into the set and the crew adores her."

In fact, the director is already thinking about casting Taylor Kinney's fiancée in the next "AHS" which has yet to be conceptualized.

Watch out for more "American Horror Story: Hotel" spoilers which will be published here when they come along. The series will premiere on Oct. 7 on FX.
