Showrunners can’t pull the wool over our eyes: We know that most of the guys and gals who play teenagers on the small screen aren’t actually in their teens. In fact, if any of the following actors were still in high school, they’d be repeating their senior year for, like, the tenth time. Maybe it’s that people are just looking younger these days (with the exceptions of Lindsay Lohan and Courtney Stodden), or maybe we’re all experts at suspending our disbelief while watching our shows. Whatever it is, we don’t mind that people in their mid-20s and early 30s are trying to pass for high schoolers.

Satisfy your curiosity and read on for the real ages of the actors who play your fave teen characters.
