Let's make this birthday one to remember.

49 years old (Born on March 23, 1976)

Happy Birthday, Keri Russell! From your iconic curls in "Felicity" that sparked a national hair debate (seriously, who knew one haircut could cause such drama?), to captivating us as Elizabeth Jennings with spy-level intensity on "The Americans," you've always kept audiences guessing and glued to the screen.

Recently dazzling fans again by stepping into galaxies far away ("Star Wars") and thrilling action-packed adventures like "The Diplomat," you continue proving there's nothing you can't handle—whether it's espionage or intergalactic diplomacy. Here's hoping this birthday brings fewer undercover missions but just as much excitement!

Cheers to another year of brilliance—and maybe less controversial hairstyles?
