Let's make this birthday one to remember.

56 years old (Born on January 22, 1969)

Happy birthday, Olivia! From "Conan the Destroyer" to enchanting audiences as Karen Arnold in "The Wonder Years," you've gracefully conquered both barbarian kingdoms and nostalgic comedy alike. We're still wondering how Conan kept up with your talent—or if Kevin Arnold ever fully grasped just how cool his sister was!

Whether acting or mesmerizing us through songwriting and singing, you've consistently delighted fans everywhere you go. May this year bring roles as legendary—and sword-swingingly fun—as those from your cinematic past. Here's hoping today feels timelessly epic—just like every memorable performance of yours we adore so much!
