Some beloved longtime “Saturday Night Live” cast members won’t be returning for Season 51, including eight-season veteran Heidi Gardner.

“SNL” creator Lorne Michaels told Puck he’d shake things up ahead of the next season of the iconic comedy sketch series.

Cast members Devon Walker, Michael Longfellow, and Emil Wakim, along with writer Celeste Yim, have also revealed their exits from the esteemed comedy platform.

Here’s who’s leaving:

Heidi Gardner

Gardner will not be returning after a remarkable eight-year tenure on the “Saturday Night Live” stage, NBC News has confirmed. Her departure was initially reported by Variety.

NBC didn’t comment publicly on Gardner’s departure. Gardner hasn’t spoken about her exit. She made her “SNL” debut in 2017 in Season 43.

She was the longest-tenured female cast member during Season 50, according to Rolling Stone.

Gardner appeared in numerous sketches and was recognized for her “Weekend Update” roles, including “Bailey Gismert,” an awkward teenage film reviewer, and “Angel, Every Boxer’s Girlfriend from Every Movie About Boxing Ever.”

Outside of 30 Rock, Gardner has a thriving career, featuring in the Apple TV+ series “Shrinking” and films such as “Hustle,” “Life of the Party,” and “Trust Fall.”

Devon Walker

Walker announced his departure Monday on Instagram, with the caption: “me and baby broke up.”

“To me, jobs in this industry feel like a series of little marriages. Some endure for a long time if we’re fortunate, but most are ephemeral,” he expressed. “The show and I spent three years together, and it was sometimes amazing. Other times, it was quite toxic. But we made the most of it, despite all the dysfunction.”

Michael Longfellow

Longfellow called his tenure “the best three years of my life so far.”

“Won’t be returning for a 4th season at SNL. I wish I was, but that’s how it is,” he shared on Instagram Thursday. “I have nothing but gratitude for the experience and everyone involved. Lorne, you gave me the best job in the world and transformed my life. You even put my mom on TV. Thank you doesn’t start to cover it, but thank you.”

Emil Wakim

Wakim, a featured player on the show, said Wednesday “it was a gut punch of a call” to learn he won’t return for “SNL’s” next season.

“Every time i scanned into the building i would think how insane it is to get to work there. it was the most terrifying, thrilling, and rewarding experience of my life and i will miss it dearly and all the brilliant people that work there that made it feel like a home,” Wakim wrote on Instagram.

“i was so lucky to bring some of myself in there and say things i believed in and i’m excited for whatever chapter comes next. here’s to making more art without compromise,” he added.

Celeste Yim

Yim bade farewell to the show after five seasons as a writer, saying the job “literally made all of my dreams come true BUT it was also grueling.”

“I loved it and I laughed every day and it’s where I grew up,” Yim wrote Sunday on Instagram.

Yim also noted that they are the “first ever out trans person to be a writer for SNL.”

”I always felt honored to be working within the long tradition of queer writing at the show,” Yim wrote. “I feel so powerless to protect trans people in the world but writing connects us and makes us permanent, so it’s what I will continue to do.”

Season 51 premieres Oct. 4 on NBC.
