After months of speculation over the theme of American Horror Story season eight, series co-creator Ryan Murphy finally put fans out of their misery and announced on Twitter what we could expect when it returns later this year.

"The Coven/Murder House AHS crossover season won't be happening next year...because it's happening THIS YEAR. AHS #8 WITCHES RULE THIS SEPTEMBER."

Murphy previously teased that an AHS crossover season was in the works back in 2016, but he was keen to stress that it wouldn't happen until season nine. At the time he wasn't giving away which two seasons would be in for a mash-up. However, earlier this year, Murphy confirmed that he was primarily looking at Murder House (season one) and Coven (season three).

"It’s a character from season 1 that will be thrust into the world that you are left with at the end of Coven, which is sort of like the male/female/witch academy. And then all of those characters will intertwine, which is confusing because some of them are from seasons 1 and 3. Like, Sarah Paulson will probably be playing 18 characters."

AHS regulars Sarah Paulson, Kathy Bates, Evan Peters, Cheyenne Jackson, Billy Eichner, and Leslie Grossman are already onboard for season eight, and production is expected to kick off sometime over the summer.

Ryan Murphy recently joined Shonda Rhimes, Jenji Kohan as the latest big name creative force to be snapped up by Netflix in an unprecedented deal worth a reported $300 million. Murphy already has two Netflix shows on the way with One Flew Over the Cuckoo's Nest prequel series Ratched starring Sarah Paulson in the role that won Louise Fletcher an Academy Award. Meanwhile, the political comedy The Politician is aiming high with  Barbra Streisand and Gwyneth Paltrow reportedly in talks to appear.

The still-untitled eighth season of American Horror Story will debut of FX later this year.
