You're going about this all wrong, here's my advice:
First off, get the girl to wear a ton of make-up, the trendiest trainers around, a very revealing top and shorts so high her butt cheeks hang out of the bottom.
Get Labrinth to do the production.
Replace the verses with Tinie Tempah rapping.
Change some of the chorus lyrics to include phrases like, "Do it like a boss", "droppin' low" and compare yourself to some cool people E.g. "Doin' it like Kurt Cobain".
The video needs to include street scenes of deprived areas, cars bouncing, some muscley bloke with his top off sweating and working out in a gym or boxing club, slutty looking girls, slow-mo shots of the singer but with the mouth in time to the music and finish with a shot of her standing on a tall building roof with her arms outstretched, the camera panning backwards slowly revealing a sunset on the horizon.
