For her first performance of "Collide", Leona Lewis took the stage on (shocker!) Simon Cowell's new game show Red Or Black. Yes, game show. LOL & to explain the briefcases (which I thought were cool enough to begin with), I had to post this video... are they really gonna have a musical guest every episode JUST to choose a briefcase?! Only Simon... Leona sounded & looked GREAT though! "Collide" is the first single off her upcoming third album Glassheart, which drops on November 28th in the UK.
