If someone went back in time and told 13-year-old Katy Perry that she would become a pop star when she grew up, she would probably have been thrilled. In this photograph, that Katy posted on Instagram, we can see teenage Katy singing into a mic, preparing for her future career.

She really looks just like a normal kid, proving that you really can grow up to be anything you want. The Firework singer is also finding success in her personal life, recently getting engaged to actor Orlando Bloom.
