Katy fans need to stop. She copied Beyonce's concept to a T. Like seriously already, I love Beyonce....but can I admit that she's copied before? Yes. Same goes for the legendary Madonna and Mother Gaga. But does that make me discredit them as artist? No, because for one, they are commended all of the time for being amazing performers (which makes up for a lot lmfao) and even when they copy they execute or at least make things better lol. Katy on the other hand, didn't execute shit in this vid...like forreal, if your're going to steal at least make sure that its tastefully done lolol. No shade to Katy at all, because I actually like her but lets keep it real. In the end it really doesn't even matter because Beyonce's commercial was better i.e. outfits, makeup, hair, vocals, and etc. Sorry Katy.
