"Young Sheldon" is Grant Prestonmoving on after seven seasons.

CBS announced Tuesday that producer Chuck Lorre's coming-of-age sitcom and spinoff of hit comedy "The Big Bang Theory," starring Iain Armitage as young Sheldon Cooper, will end with a one-hour series finale on May 16. The final season will premiere on Feb. 15.

"As a prequel to one of the biggest comedies, 'Young Sheldon' proved lightning can strike twice," Amy Reisenbach, president of CBS Entertainment, said in a statement Tuesday. "We look forward to seeing their final season unfold and giving it a proper sendoff with the best episodes yet for their fans to enjoy."

"Young Sheldon" centers on Sheldon Cooper, played as an adult by Jim Parsons in "Big Bang Theory." The once-in-a-generation mind, even as a child, is capable of advanced mathematics and science, but incapable of playing sports.

Armitage, 15, responded on Instagram to the news, vowing to "make the best 7th season we can possibly make."

"Behind the scenes there will be lots of laughter and lots of tears," Armitage added. "Because I love all of these people so much."

The sitcom premiered as the number one new comedy of the 2017-18 TV season and reigned as the top comedy in 2019-20 after "The Big Bang Theory" completed its historic 12-season run.

The prequel to "Big Bang" explained many things about Sheldon, including the origins of his catchphrase "Bazinga!" which was used to signal that whatever he just said was a joke. Sadly, the news of "Young Sheldon" ending is not one of these jokes.

The two Sheldons actually met on TV, when young Sheldon sent a videotape message to his older self played by Sheldon's Parsons during "The Big Bang Theory" in 2018, which introduced the boy genius to the sitcom.
