While Lady Gaga is barreling ahead with her crusade to save The Gays and Shakira is juggling popstar commitments with her role as UNICEF ambassador, Katy Perry is happy to concede that her music is not going to change the world.
Speaking to Rolling Stone, she said: "I'm not a dummy. I know 'California Gurls' isn't going to save the world, but I got a lot of heart from my upbringing and I put a lot of heart in my songs."
Questioned about negative critical reactions to her music, she responded: "Whenever people ask me about having bad reviews, I'm like, 'Have you seen the run I've had? Have you see the numbers?' Numbers do not lie!"
