We all know her as the girl who could shut down a boy genius with a single, devastating eye-roll. For seven seasons, Raegan Revord didn't just play Missy Cooper; she basically became the patron saint of every sibling who ever felt overshadowed by a "gifted" brother.
But here is the thing: the girl behind the sass is way more complex than the character she played on CBS. Now that Young Sheldon has wrapped and the dust has settled on that emotional series finale, the Missy Young Sheldon actor is moving into a phase of life that looks nothing like the suburbs of East Texas.
The Girl Who Outsmarted the Genius
It is honestly wild to think that Raegan Revord was only nine years old when she landed the role of Missy. Most kids that age are struggling with long division. Raegan, meanwhile, was mastering the art of the deadpan zinger.
While Iain Armitage had the heavy lifting of all that scientific jargon, Revord had the harder job: making us care about the "normal" kid. She brought a specific kind of spunk that kept the show from becoming too clinical. If Sheldon was the brain of the house, Missy was undeniably the heart—and occasionally the middle finger.
Why we loved her version of Missy:
- The Accent: She actually learned that iconic Texan drawl by watching Laurie Metcalf (who played the older Mary Cooper in The Big Bang Theory).
- The Relatability: She represented everyone who just wanted to go to a party or watch MTV while their family argued about physics.
- The Growth: By the final seasons, Revord was portraying a teenager dealing with real grief, especially after the loss of George Sr.
Life After the Cooper House
A lot of child actors sort of fade away after a big hit. They take a long vacation, or maybe they just disappear into the "where are they now" listicles. Not Raegan.
In a move that surprised a lot of people, she didn't just jump into another sitcom immediately. She became an author. Like, a real-deal novelist. Her debut book, Rules for Fake Girlfriends, hit shelves in late 2025. It’s a young adult rom-com set in England, and it’s actually really good. It deals with grief, scavenger hunts, and finding yourself—stuff she definitely knows a thing or two about.

Coming Out and Coming Into Her Own
2025 was a massive year for the Missy Young Sheldon actor. Beyond the book launch, Raegan shared something deeply personal with her fans: she came out as non-binary and uses they/them pronouns.
Growing up in front of millions of people is a special kind of pressure cooker. To do that while also figure out your identity? That’s some serious courage. Fans have been incredibly supportive, mostly because Raegan has always been so authentic on social media. They don't post the "perfect" Hollywood life. They post about their five pets, their book club (Read with Raegan), and their work with Children’s Hospital Los Angeles.
What’s Next for Raegan Revord?
If you’re missing Missy, you don’t have to look too far. While the main show is over, Raegan has been popping up in the spin-off Georgie & Mandy’s First Marriage. Seeing the "adult" version of Missy start to take shape is a treat for anyone who followed the Coopers for a decade.
But acting is just one piece of the puzzle now. There are rumors of a fantasy novel in the works. They’re also getting more involved in directing. Basically, Raegan Revord is proof that being the "twin sister" was just the opening act.
