She’s baaaaaack.

Like a bad penny, Ally Sheedy is set to return to Psych for Season 7 — and not for any garden-variety episode either.

TVLine has confirmed that the onetime Brat Packer will reprise her role as criminal mastermind/serial killer Yang in the USA Network series’ two-hour musical episode.

Sheedy’s latest encore was being kept under wraps — that is, until Psych star Dulé Hill shared a photo of her on set via Twitter, with the hashtags #AllySheedy and #PsychMusical.

Rocky Horror Picture Show alum Barry Bostwick recently signed up to play a Santa Barbara theater owner in the singing-and-dancing event; Brooke Lyons (2 Broke Girls) and Anthony Rapp (Rent) will be on (jazz) hand for the special, as well. And, in keeping with the series’ affection for all things Breakfast Clubby, Anthony Michael Hall is set to show up in Season 7 — though not necessarily during the musical — as an oddball police consultant.
