The creepshow’s co-creator, Ryan Murphy, announced on Twitter Tuesday morning that the “Rhiannon” songstress has agreed to make a guest appearance. No word yet on whether she’ll be warbling one of her hits — or even if she’ll be real or a figment of Misty’s vivid imagination — but regardless, Murphy has pulled off what is likely the (spell) casting coup of the year!
