4-Year-Old Kai Sings Bruno Mars on Ellen [VIDEO]

Recently, four year old Kai stole the Ellen show when he appeared to sing Bruno Mars' song "When I Was Your Man". He was discovered on YouTube when he was singing another Bruno hit, "Grenade".

Kai ends up stealing the show, especially when he grabs Ellen's hand during the song, but the coolest thing happens on his way home back to San Antonio. Ellen has the update in the second video.
