Kai is a small singer with some big dreams! The 8-year-old was on Ellen the other day and soon leapt into a cover of "Thinking Out Loud." He got so into it, that he didn't even see who was sitting right behind him! Apparently, Ed was scheduled as the other guest on that day's show and was watching the live feed in his dressing room as Kai was serenading Ellen, so he decided to pay him a little visit. So sweet!
On a side note, how adorable is it that all this kid wanted for his birthday is, "a baby brother that is five-years-old"? Check out Kai's previous appearance on Ellen below.
