"American Horror Story: Apocalypse" is bringing back Stevie Nicks, and we officially know when.

Series creator Ryan Murphy announced the music legend's return in August, and in an Instagram post on Wednesday, Oct. 10, he nailed down the episode in which she'll finally be back. Murphy didn't give much notice -- his post came just hours before the episode's broadcast.

Nicks will appear in "AHS: Apocalypse" Episode 5, "Boy Wonder." Murphy's post included a photo of her in a witchy outfit and said, "She returns tonight."

In "AHS: Apocalypse," the Grammy winner is reprising her guest role from "Coven." Her character is a fictionalized version of herself, one with special powers. She shares Nicks's real-life musical superpowers, too, and the singer even performed songs on the show. If we're lucky, she'll do so again.

Nicks is one of many "AHS" vets to partake in the "Murder House"/"Coven" season. Others include Jessica Lange, Connie Britton, Dylan McDermott, Sarah Paulson, Kathy Bates, Evan Peters, Emma Roberts, Lilie Rabe, and many more.

"AHS: Apocalypse" airs Wednesdays at 10 p.m. ET/PT on FX.
