He has the hat. He has the swagger. 4-yr-old Kai is just a few decades away from being the next Bruno Mars. We can tell. Here he is performing on "Ellen."
From the "Ellen" YouTube page:
Kai, from Woodland, TX, initially won Ellen's heart when he sang "Grenade" back in January. Now he's back to serenade America once more and we're really, really happy he did.
