And so the ending begins: The stars of "The Big Bang Theory" have started taping the comedy's 12th and final season, and they're going to have us all in our feelings.

News came Wednesday that the CBS show will end after Season 12, adding another emotional layer to the cast's tweets about kicking off taping. Now that we know for sure that the series has an end date, the photos they've posted are suddenly bittersweet. Just look at their recent posts:

Kaley Cuoco addressed the show's end directly, calling the experience "a dream come true and as life changing as it gets." She promised that they plan to make the upcoming season the best one yet and that they're "drowning in tears." Rest assured, fans, you're not alone.

"The Big Bang Theory" was a surprise hit when it began in 2007, and it has enjoyed a successful run in the years since. Alas, though, the stars are moving on, but at least they're bringing us along with them.

"The Big Bang Theory" returns for its final season on Monday, Sept. 24 at 8 p.m. ET/PT on CBS.
