Stevie Nicks should really guest star on every TV show as herself. Last night on “American Horror Story: Coven,” the “white witch” showed up to serenade her old friend, coven Supreme, Fiona, and die-hard fanwitch, Misty, with a version of “Rhiannon.” If that weren’t enough, Stevie also showed Misty how to do her signature move, the shawl twirl, and gifted the young witch with her signature item, which no doubt is filled with all sorts of white magic. Sadly, Madison convinced Misty that “players only love you when they’re playin’” and that Stevie probably had tons of other superfans who she played private concerts for (ME! ME! PLEASE!). But Madison was playin’ her. She knocked Misty out cold and stole the shawl — nice hustle, girl! — and Stevie was left to play once again for Fiona. Best use of a TV plot involving Stevie Nicks and her music. You can relive the white witch’s version of “Has Anyone Ever Written Anything For You” after the jump.
