The actress — who scored a second-consecutive Emmy nod for her work on the Fox hit — will appear in a nightclub scene with series leads Kristen Johnston, Donald Faison, Wayne Knight, David Alan Basche and Kelly Stables, as well as guest star Amanda Detmer, who is playing Johnston’s perfect sister Jill.
The episode, which also features the return of Judith Light as Johnston’s mother, is slated to air Aug. 22.
Last month, Jones confirmed to TVLine that she’ll be returning to Glee this season. “I don’t know how many episodes,” she said. [But] I definitely know I’m coming back as a guest star.”
