The Marvelous Mrs. Maisel” is adding “Gilmore Girls” star Kelly Bishop to its cast for Season 4.

Bishop will appear in Season 4 of the critically-acclaimed Amazon series in a guest starring role, though the exact nature of what that role will be are being kept under wraps.

The role reunites Bishop with “Maisel” team Amy Sherman-Palladino and Daniel Palladino, who all previously worked together on “Gilmore Girls” as well as the short-lived sitcom “Bunheads.” Bishop is now the second “Gilmore Girls” alum to join Season 4, with Milo Ventimiglia also set to appear in a guest role. Production is currently underway on the new season in New York City.

Bishop is perhaps best known for her role as family matriarch Emily Gilmore in “Gilmore Girls,” a role she reprised in the Netflix series “Gilmore Girls: A Year in the Life” in 2016. She is also known for her role in the beloved film “Dirty Dancing.” Bishop is a Tony Award winner as well, having won the award for best featured actress in a musical for her role in “A Chorus Line.”

She is repped by A3 Artists Agency.

“The Marvelous Mrs. Maisel” was created by Sherman-Palladino, who executive produces along with Daniel Palladino. Rachel Brosnahan stars as the titular Mrs. Maisel, with the show also starring Alex Borstein, Tony Shalhoub, Marin Hinkle, Michael Zegen, Kevin Pollak, Caroline Aaron, and Jane Lynch.

To date, the series has won 20 Emmy Awards and three Golden Globes, including wins at both awards shows for best comedy series. Borstein has twice won the Emmy for best supporting actress in a comedy, while Brosnahan, Lynch, Shalhoub, and guest star Luke Kirby have also picked up statuettes for the series.
