It’s Chris Colfer (Kurt)
Come on now: If you know anything at all about Chris Colfer (Kurt), this should come as no surprise. At only 22 — making him multiple years younger than most everyone else on the list — Chris not only stars on Glee, but is already the author of two books (with more on the way), and is about to make his big screen debut in Struck By Lightning, a film he both wrote and stars in.
That’s not a bad list of accomplishments for someone at any age, much less a guy who only reached the legal voting age about a year ago. Congrats to Chris on all his success!
