The young singer also reveals all about how he met the 'Doo Wops & Hooligans' singer.
A four year-old Bruno Mars fan stopped by the Ellen DeGeneres show this week and performed a rendition of 'When I Was Your Man' to the chat shot host.
The young star has been a guest on her show before and this time revealed all about the time he met his musical icon on a plane.
"I was taking a nap and my mummy woke me up because she saw Bruno Mars – she was walking to the bathroom. And Bruno said 'Hit it Kai'," reveals the youngster of his meeting with his hero before explaining that he then started singing for him.
The four year-old also had on a signature Bruno fedora hat and presented Ellen with matching bracelets during an adorable exchange.
He also took her by the hand during the song and was greeted with a huge applause following his performance.
