Spoilers and rumors surrounding the storyline for "American Horror Story" season 5 point to satanism as the overriding theme for the Ryan Murphy series.

The "American Horror Story" season 5 Reddit page has the link to a Tumblr page which dished major spoilers, particularly on the role of Lady Gaga.

According to the rumor, based on the feed from an "IMDb Fx insider," Lady Gaga will star in "AHS" for at least three seasons, and the earlier reports about "Hotel" being a musical were false.

The Tumblr post claimed that Lady Gaga "beautiful strange, yet sophisticated heiress - knees deep in debt - who runs the hotel and will do whatever it takes to keep it up and running, regardless of the tragic and disturbing events that have taken place there."

Instead of the supernatural, "American Horror Story" season 5 will be more grounded as it will deal with a satanic cult, alongside "corrupt politicians, secret societies, and other strange guests" frequenting the hotel.

Lady Gaga's character knows the strange things happening in her hotel but she allows them "only if they begin to pay more."

The spoilers for "American Horror Story" season 5 also hinted that Jessica Lange will return for a brief moment as the older Lady Gaga "who kicks off the new story by telling it to a few characters."

"American Horror Story: Hotel" will take place in modern time but there would be plenty of flashbacks to the 70s and 80s to set up the story. The plot will center on a young couple who finds out the strange events inside the hotel but they will be caught in a "dark force that won't allow them to leave," the Tumblr post alleged.
