Katy Perry dissed by Lady Gaga at SXSW

Looks like Lady Gaga may be stirring rumors of a feud between herself and fellow pop singer Katy Perry again after a comment during her South by Southwest keynote interview. The Applause singer gave her keynote presentation Friday morning at the Austin (Texas) Hilton's Grand Ballroom, Billboard reported. Speaking of comparisons made between herself and other female pop musicians, Lady Gaga made a reference to Perry. "I don't know what the [expletive] I have to do with Katy Perry," she said. "Our music is so completely different. I couldn't be more different, really. I really don't fit in pop music in a way, but I came through it and I'd like to think I changed it in some way so you can feel like you don't have to fit into a mold." "The truest way for us to maintain the music industry is to put all of the power back into the hands of the artists," she added of the music industry. "If we are not telling our artists to be creative, what are we? What are we doing? Why is it a prison, and why are we allowing it to be a prison?"
