Perry, who used to front the short-lived rock band 4 Non Blondes and went on to write hits for Pink and Christina Aguiliera, among others, was asked, "Linda, how do you feel about Beyonce changing one word on a song and getting writing credit. Does that bother you as a songwriter?"

Perry's response: "well hahaha um thats not songwriting but some of these artists believe if it wasnt for them your song would never get out there so they take a cut just because they are who they are. but everyone knows the real truth even Beyonc�. She is talented but in a completely different way."

There's been much speculation over the years as to what a Beyonc� songwriting credit actually means. On her 2011 album, 4, her opening track, "1+1″ bore quite a bit of resemblance to the The-Dream's song "Nothing But Love," but her name was added to the songwriting credits. Listen to both songs here.
