Let's make this birthday one to remember.

40 years old (Born on March 26, 1985)

Happy Birthday, Jonathan Groff! From your electrifying debut in "Spring Awakening" to charming us all as Kristoff's voice in "Frozen," you've proven that reindeer whispering and Broadway belting can indeed coexist. Your talent is so versatile; we're still humming along while wondering how you manage to make every role unforgettable.

Recently, your captivating performance in "Mindhunter" had audiences glued—and slightly terrified—in the best possible way. Whether you're profiling serial killers or serenading snowmen, one thing remains clear: age only makes you more fabulous (and funnier). Here's hoping this birthday brings fewer interrogations and plenty of cake—happy celebrating!
