2U David Guetta Feat. Justin Bieber
Dot Cotton is featuring on a record... We don't know what it sounds like, but DJ Dan Kelly mocked up what it should be like!
Katy and Posh Ben left Dan in the studio on his own last week... And he did this.
Yep, DJ Dan Kelly mashed up Dot Cotton and the wedding dancefloor smash hit, Cotton Eyed Joe.
It sounds ridiculous... But it's actually pretty catchy!
