Big Bang Theory Stars Jim Parsons and Mayim Bialik Are Set to Reunite on Young Sheldon

Huge news, Big Bang Theory and Young Sheldon fans.

Jim Parsons and Mayim Bialik—who played Sheldon Cooper and Amy Farrah Fowler on the series that started it all—will reunite for the first time since The Big Bang Theory’s series finale in 2019. The pair will reprise their roles for yet another series finale, joining the cast of Young Sheldon as they take their final bow on Thursday, May 16. (Warning: Basic Big Bang Theory spoilers beyond this point.)

For seven seasons the prequel series Young Sheldon followed the childhood origin story of theoretical physicist Sheldon Cooper, played by Iain Armitage. However, before audiences fell in love with the entire Cooper family, they were introduced to adult Sheldon through Jim Parsons on The Big Bang Theory, which aired for 12 seasons from 2007 to 2019.

During the course of the hit sitcom, viewers watched as Sheldon fell in love with neuroscientist Amy Farrah Fowler, beginning with a blind date in the season-three finale, “The Lunar Excitation,” which also marked Bialik’s first appearance on the series. “Shamy” became a fan-favorite couple as their love story survived ups and downs, including breakups, love confessions, and a wedding in season 11.

Parsons serves as an executive producer and narrator of Young Sheldon, while Bialik has appeared in two episodes via voiceover. During one of those episodes, adult Sheldon revealed that he and Amy have a son named Leonard Cooper, named after Star Trek actor Leonard Nimoy…and yes, that means their son has the same first name as Sheldon’s best friend Leonard Hofstadter (Johnny Galecki).

While CBS is keeping the details of their onscreen reunion under wraps, there’s no doubt fans of the original series will be thrilled to see the TV couple back on their screens.

The series finale of Young Sheldon airs on Thursday, May 16 at 8 p.m. ET on CBS and will be available to stream on Paramount+.
