I'm convinced Katy Perry uses all the colours and visual aides to distract us from how basic she really is.
Singing Birthday- sure to be her next number 1- at the Billboard Awards, the Diva had a backing track so layered that I couldn't even tell when she was singing most of the time. Her dancing was also pretty listless; but the peppy attitude does wonders compensating for that. The Diva did manage to give us some good stuff, vocally, at the end of the song, though- so stay tuned for that!
As for the weirdness of bringing a minor onto a stage with pole dancing men and all this innuendo going on, I'm not even going to go there!
