Let's make this birthday one to remember.

29 years old (Born on November 23, 1995)

Happy Birthday, Katherine McNamara! From your strawberry-blonde charm in "Contest" to battling monsters (and teenage drama) effortlessly in "Girl vs. Monster," you've proven that comedy and courage go hand-in-hand—especially when you're the one holding the script.

Whether matchmaking hearts as Mary or lighting up screens on New Year's Eve, you always leave audiences smiling brighter than a birthday cake full of candles. Here's hoping this year brings even more memorable roles—and fewer monster battles off-screen!

Keep shining bright; Hollywood wouldn't be nearly as fun without your witty comebacks and timeless charisma. Cheers to another fabulous trip around the sun!
