Katy Perry took to her Twitter yesterday to hate on Lady Gaga's "Alejandro" video. Evidently, Katy was a little offended by Lady Gaga's use of the catholic church. She tweeted, "Using blasphemy as entertainment is as cheap as a comedian telling a fart joke." Who knew Katy was so religious? Maybe she's just a little jealous that there isn't half as much hype over her video premieres as there is for Gaga.. Gaga is Queen, Katy. Where have you been?
