Koen may only be 3 years old, but he already knows the words to one of the biggest songs from the long-running Broadway musical, "Les Misérables."

His mother, Erin Frehner, uploaded a video of her adorable son singing "Do You Hear the People Sing" to YouTube on August 25. Koen starts quietly, but then BELTS out the words like he's been doing it onstage for years. Oh, and the best part? He knows them all by heart. Koen didn't need any help or prompting from his mother. Basically, he straight-up slayed.

Vive La France!
