You might remember that Debbie played Grace’s mom Bobbi Adler on the original run of the sitcom.
Billie will tape the episode of September 25 and Fiona will be reconnecting with her “cool aunt,” according to Deadline.
“The episode is especially meaningful because of Billie’s relationship to the show,” Will & Grace co-creator/executive producer Max Mutchnick said. “We’re thrilled to have Billie. And best of all – she’s really good.”
You can also see Billie right now on the FX series American Horror Story: 1984.
