Let's make this birthday one to remember.

43 years old (Born on March 04, 1982)

Happy Birthday, Peter Hollens! Another year older and still pitch-perfect—no instruments required. From your incredible acappella covers that have enchanted millions on YouTube to those unforgettable harmonies with On the Rocks in "The Sing Off," you've proven time and again that you're truly a one-man orchestra.

Here's hoping this birthday hits all the right notes (pun absolutely intended). May you continue creating musical magic, inspiring countless fans worldwide, and reminding us all how much cooler it is when voices alone can rock harder than any band. Keep singing loud—and remember: aging gracefully means never missing a beat!
