Mom is leaving CBS' nest.

The broadcast network announced Wednesday that its Chuck Lorre comedy starring Allison Janney will end in May after eight seasons.

“For the past eight years, we’ve had the great honor to bring these wonderful characters to life, sharing their struggles and triumphs with millions of viewers every week,” said executive producers Lorre, Gemma Baker and Nick Bakay. “From the beginning, we set out to tell stories about recovery from alcoholism and addiction that are rarely portrayed in a network comedy series. Whether it was the emotional reactions of the live audience on tape night inside Stage 20, or discussions at The White House regarding the opioid crisis, or the personal stories we continue to receive on social media, we take great pride in knowing Mom has positively impacted so many lives. We are forever grateful to our brilliant cast and guest stars, wonderful writers, and amazing crew for going on this journey with us.”

The news comes months after co-star Anna Faris stunned the industry and announced she would not be returning for the multicamera comedy's eighth season.

“Since its premiere, Mom has touched people’s lives by sensitively tackling weighty yet relatable topics, with a perfect, deft touch,” said Kelly Kahl, president, CBS Entertainment. “Mom redefined what a comedy can be, and we are proud to have been the network home to this wonderful series. We are deeply grateful to Chuck Lorre and his tremendously creative production team, helmed by Gemma Baker and Nick Bakay, and the amazingly talented cast, led by the phenomenal Allison Janney.”

The decision to end Mom, currently CBS' longest-running scripted comedy series, arrives hours after the network handed out early renewals to Lorre's Bob Hearts Abishola and Jim Reynolds' The Neighborhood. Lorre's Big Bang Theory prequel Young Sheldon is awaiting word on its fifth season; rookie B Positive was picked up for a full season and fellow freshman United States of Al will debut in April. All hail from Lorre's longtime home at Warner Bros. TV.

“Chuck, Gemma, Eddie and Nick have created a beautiful series with storylines depicting the real-life struggles and successes of those in recovery," producers Warner Bros. TV said in a statement. "We are deeply proud of the Mom cast, crew and writers for the impact their work has had, and will continue to have, on viewers around the world, and we thank our partners at CBS for enabling these stories to be told.”

The Mom series finale will air Thursday, May 6, at 9:01 p.m. on CBS.
