What's better than Bruno Mars singing "Uptown Funk?" His mini-me, Kai, singing "Uptown Funk" WITH Bruno.

The 6-year-old frequent "Ellen Show" guest and Bruno Mars fan recently paid a visit to Ellen, and on the show the host shared a video of Kai getting to meet the singer. The adorable clip shows Kai sitting next to Bruno on a couch, and after hugging it out ...

... they burst into singing "Uptown Funk" together -- Bruno's latest hit with Mark Ronson -- and it was ADORABLE! To top it off, Kai had his Uptown Funk style going on with his fedora.
