Let's make this birthday one to remember.

27 years old (Born on August 16, 1997)

Happy Birthday, Jack Met! The "J" in AJR might stand for Jack, but we all know it secretly means "Joyful," "Jovial," or maybe even "Just-can't-stop-dancing." From your energetic stage presence to your iconic hat collection, you've given fans countless reasons to smile and sing along. Whether you're bouncing around performing hits like "Bang!" or making us laugh with your quirky TikTok antics, you truly are the heartbeat of AJR.

Here's hoping this birthday is as unforgettable as the moment you guys topped charts with songs like "World's Smallest Violin" and rocked sold-out arenas worldwide. Keep bringing that youthful spark—after all, being the youngest brother means you'll always have bragging rights (and probably fewer gray hairs). Cheers to another year of catchy tunes and hilarious sibling banter!
