Let's make this birthday one to remember.

43 years old (Born on March 28, 1981)

Happy Birthday, Julia Stiles! From teaching us the art of sarcastic wit as Kat Stratford in "10 Things I Hate About You," to keeping Dexter Morgan on his toes (and ours!) as Lumen Pierce—your talent for portraying strong and unforgettable characters is unmatched. We still can't decide what's more impressive: your Shakespearean sass or your ability to survive a season alongside everyone's favorite serial killer.

Here's hoping this birthday brings you fewer dramatic plot twists than your roles usually demand—but just enough excitement to keep things interesting. May your day be filled with laughter, cake, and absolutely zero reasons to list ten things you hate about anything!
