Bruno Mars & Mark Ronson Take 'Uptown Funk' To Another Level On Ellen

The duo are on course for their SIXTH week at the top of the Big Top 40 and have now boosted their chances with an appearance on ''Ellen'.

It's the hottest record in the world at the moment and it doesn't look like it'll be losing it's crown any time soon. Mark Ronson & Bruno Mars took to the stage on 'Ellen' to perform the current Vodafone Big Top 40 No.1.

The duo were in fine form with not only a stellar performance but a healthy dose of audience interaction. Even Ellen got into the groove with a small dance cameo.
