Last week, 'American Horror Story: Coven' creator Ryan Murphy delighted fans of both the FX horror-drama and Fleetwood Mac alike in revealing that singer Stevie Nicks would appear on the series, having been referenced by Lily Rabe's Misty Day all season long. Now, the "White Witch" herself has arrived on set, looking supernaturally good for her age!

Ryan Murphy himself tweeted out the photo of Nicks' appearance on set, looking surprisingly youthful and fashionable for a 65-year-old. As we learned previously, the Fleetwood Mac singer will appear in an upcoming episode as herself, as part of Fiona's bid to coax Misty Day into revealing herself as the true Supreme:

It’s part of Fiona’s ruse in that Fiona is trying to get the true Supreme to reveal herself because she needs to stay alive. So she tells Misty Day that the Supreme gets so many great things in life, like tickets to the Oscars and Met Ball tickets. So she brings Stevie Nicks in as a gift to Misty to prove to her that if she exhibits more power she’ll get that and more. Then the other girls come home and see Stevie and Misty singing and it starts them trying to move much quicker to prove that they are the Supreme.
