The cast shakeup at Saturday Night Live is turning into an earthquake.

The latest performer to exit the show is Heidi Gardner, who will depart after eight seasons on SNL. She joined the NBC series in the 2017-18 as a featured player and moved up to the main cast two seasons later.

Gardner is the fourth SNL castmember to leave the show in the past three days, following Devon Walker, Emil Wakim and Michael Longfellow out the doors of 30 Rock. She had been the longest-tenured female member of the show’s current cast, a designation that will now fall to Ego Nwodim.

NBC declined comment.

Executive producer Lorne Michaels told Puck in an interview last week that cast changes for the 51st season, which premieres Oct. 4, were likely. The four departures (so far) ahead of the season are the most since 2022, when eight people left the cast between the end of season 47 and the start of season 48.

Gardner built up a number of recurring characters on SNL, including “Weekend Update” staple Angel, aka Every Boxer’s Girlfriend in Every Boxing Movie; teenage movie critic Bailey Gismert; and newswoman Bobbi Moore — most notably in 2024’s “Beavis and Butt-head” sketch that featured Gardner breaking at the sight of host Ryan Gosling and castmember Mikey Day made up as the two MTV characters. She also played Kim Kardashian, Jill Biden, Kristi Noem and Taylor Swift at various points in her eight seasons.

Outside of SNL, Gardner’s credits include a recurring part on Shrinking and guest roles on You, Superstore and Girls5Eva, as well as ad campaigns for Homes.com, Buffalo Wild Wings and Starbucks.
