Jerry O'Connell and Jim Parsons in The Big Bang Theory


Fans of "The Big Bang Theory" got sad news Wednesday when word came that Season 12 would be the show's last, and now they're left wondering why.

A new Deadline report says the decision was made after star Jim Parsons told Chuck Lorre, one of the show's creators and executive producers, that he planned to move on. The actor reportedly broke the news on Friday and stood firm on his decision over the weekend, spelling the end of the series. As Deadline notes, Lorre had previously indicated that the sitcom wouldn't continue if Parsons, Johnny Galecki, or Kaley Cuoco chose not to return.

The rest of the people who work on the show reportedly learned that the show is ending on Wednesday, and Deadline's sources say Parsons spoke to the entire cast and was "tearful." (CBS declined to comment on the news, and Moviefone had not heard back from Parsons's rep at the time of publishing.) They've been together for 11 seasons already, so it's not surprising that it was a hard announcement for him to make.

Cuoco shared in an Instagram post that her heart was "broken," but she was careful to note that it would have been no matter when "The Big Bang Theory" ended. As for Parsons, he was having a hard time, too. He wrote a lengthy post that expressed his gratitude for all the people who have worked on the show.

"I will miss all of you and all of this more than I can say and more than I can know at this time," he wrote in part.

There are a lot of people in an emotional place right now, but the good news is that we still have 24 episode of "The Big Bang Theory" to look forward to.

Season 12 premieres Monday, Sept. 24 at 8 p.m. ET/PT on CBS.
