FX has scared up a fourth season of American Horror Story.

With American Horror Story: Coven garnering higher ratings so far than either of the show's first two itinerations, the renweal decision was an easy one for FX President John Landgraf.

“Put simply, Ryan Murphy is a master television producer,” said Landgraf in a statement, confirming the creator and his entire team will return for Season 4.

“Time and time again he reinvents the form. What he, co-creator Brad Falchuk and their producers Dante Di Loreto, Tim Minear, Jennifer Salt, James Wong, Brad Buecker, Jessica Sharzer, Douglas Petrie, Alfonso Gomez-Rejon, Alexis Martin Woodall and the entire production team and cast responsible for the American Horror Story franchise have done is nothing short of extraordinary. Every year, they create a riveting and brilliant new miniseries. 

"AHS: Coven is the best yet, and I have no doubt that the next installment will be even better.”

It's far too early to know anything about Season 4 - cast, setting, theme - but 13 new episodes will air in the fall of 2014.

Until then, nine more remain of Season 3, with American Horror Story Season 3 Episode 5 on tap tonight at 10/9c.
