Watch Stevie Nicks sing in the new "American Horror Story" episode

On last night's episode of FX TV show, "American Horror Story: Apocalypse", Stevie Nicks made a special appearance as the White Witch and sang to the leading cast.

She was playing the same role as her appearance in "AHS: Coven" in 2014.

Set in a post-apocalyptic nuclear bunker, Stevie Nicks appeared at a tense moment between two factions (witches and warlocks) to sing "Gypsy". You can watch the scene in the video clip below.
