This Toddler Singing a Les Mis Tune Will Make Your Heart Swell

Kids' voices are so angelic, it's hard not to love listening to every single word that comes out of their mouths — so when a 3-year-old sings at the top of his tiny lungs with such a high-pitched, adorable voice, it makes your heart swell.

Koen Frehner is already a Les Misérables fan. In fact, he knows all the lyrics to the songs by heart, so his mom decided to tape an impromptu performance of "Do You Hear the People Sing?" It's probably the cutest thing you'll ever see, as you can feel the amount of energy and heart he's putting into the performance (arm in a cast and all).

Watch the video and look out for this kiddo on Broadway in a few years — he's going to be a star!
