Theres still no official word on when The Big Bang Theory will end, but co-creator Chuck Lorre did offer some insight on Tuesday.

Earlier this year, CBS renewed the series for Seasons 11 and 12, totaling a whopping 48 more episodes. But the question remained: Will Season 12 be the last well see of Jim Parsons, Johnny Galecki, Kaley Cuoco and crew?

During the Television Critics Associations summer press tour on Tuesday, Lorre told The Hollywood Reporter , We never really figured to be at year 11, let alone whats going to happen after 12. One could easily presume that would be the end of the series but Im just amazed were here.

Kelly Kahl, CBS Entertainment president, didnt quite put it that way on Tuesday. Per THR, when asked how long the top-rated comedy would remain on the air, she said, As long as we can go 20 years. I hope to have it as long as we can.
