Ellen had a very special guest on that loves to sing.

This is Kai and he is only four years old. He has gotten very popular on YouTube for his singing. Ellen had him on as a guest and he sang one of his most favorite songs "Grenade" by Bruno Mars.

Let me just say at four years old this kid is a better singer than me. I think he so popular because of how he gets into the song. Remember the name Kai we may be seeing him on Americas Got Talent one day.
