You might remember Kai Langer, the adorable six-year-old with a lot of love for Bruno Mars which led to him becoming besties with Ellen DeGeneres.
His parents uploaded a video of him singing the Bruno Mars hit Grenade in 2013 and this made the little boy an internet sensation.
Now Kai is back again and this time he's having the absolute lols with Bruno as they sing Uptown Funk together.
It is quite possibly the cutest thing you'll see today (in second place is Kai's reaction when Ellen gives him his very own Bruno costume).
