"Guess who's visiting the Coven? The legendary Stevie Nicks!" Murphy tweetedTuesday.
There are no details on Nicks' role yet. Dubbed "The White Witch" by Misty Day (Lily Rabe) — though confused for an American Idol contestant by Zoe (Taissa Farmiga) — the Fleetwood Mac legend is Misty's idol, so we can't wait to see how Misty reacts to meeting her in person.
American Horror Story airs Wednesdays at 10/9c on FX.
