Stevie Nicks to appear on "American Horror Story: Coven"

Stevie Nicks is already a presence on "American Horror Story: Coven," thanks to witch Misty Day's (Lily Rabe) idolization of the Fleetwood Mac singer. But now she'll be on the show in the flesh, too.

Series creator Ryan Murphy tweeted Tuesday that Nicks will appear as a guest star later this season.

Murphy did not say who the singer would play, but he did explain in a recent interview why Misty is obsessed with Nicks.

"The season really is an allegory and a metaphor for any minority group in the country where you feel alone so she's a girl that has never known any other witches and all she's ever known is Stevie Nicks," he told E! last month. "So I reached out to Stevie Nicks and asked her if we could use her music and she thought about it for a while and then she said, 'Oh okay, since it's you, I'll do it.'"

Nicks had been on tour for most of 2013 with Fleetwood Mac, but the group had to cancel their New Zealand and Australia tour dates so bassist John McVie can undergo treatment for cancer.

"Coven" is the third installment in the "American Horror Story" anthology series. Last week, it was announced the show will be back for a fourth season.
