Video: McFly “Party In The USA” with Miley Cyrus

Check out this video of McFly getting down to Miley Cyrus backstage.

The video, which we’re guessing is from one of the Rock In Rio shows, has only just started properly circulating online all these weeks later.

Tom Fletcher and Danny Jones just watch and laugh as bandmates Dougie Poynter and Harry Judd bust some serious moves.

Shortly after the shows took place, the 3am girls asked Harry what he thought of Miley’s raunchy on-stage outfit – this was one of the first opportunities for Miley to showcase her new, grown-up image.

Harry replied: “How old is she? 17! Shit. Um, quite revealing, yes,”.
