Before Georgie and Mandy’s First Marriage, there was The Big Bang Theory and Young Sheldon — but which stars have crossed over from one spinoff to another?
The Big Bang Theory, which aired from 2007 to 2019, starred Jim Parsons, Kaley Cuoco, Johnny Galecki, Simon Helberg, Kunal Nayyar, Mayim Bialik and Melissa Rauch as a group of friends made up of scientists and their significant others.
During its run, the CBS comedy won 10 Emmy Awards and spawned the prequel series, Young Sheldon. The follow-up introduced Us to Sheldon’s (Iain Armitage) brother Georgie (Montana Jordan), whose love story with Mandy (Emily Osment) set the scene for CBS’ Georgie and Mandy’s First Marriage.
Rachel Bay Jones is a perfect example of a cast member who got their start on Young Sheldon before making the move. She previously spoke exclusively to Us Weekly about which cameos she would like to see.

“If Meemaw and Audrey could get into it, that would make me really happy because I love Annie Potts more than almost anyone on this planet,” she shared in October 2024. “It would be really fun to continue to play with her. And we are promised their presence since it’s a small town, so you can’t escape all those other inhabitants.”
