With the (music) world all but falling at the feet of a certain Lady GaGa, it appears Pop princess Katy Perry is not amongst them.

This marks the second time the ‘California Gurls’ singer has hit out at GaGa. In June, immediately following the premiere of GaGa’s controversial ‘Alejandro’ video, Perry tweeted:

“blasphemy as entertainment is as cheap as a comedian telling a fart joke.”
