How do I become a kid celebrity like hanna Montana

Hannah Montana is a fictional character. If you want to be famous like Miley Cyrus (the one who plays "Hannah Montana"), then have a father with a one-hit-wonder (Billy Ray Cyrus and his song "Achy Breaky Heart").

It's too late, you needed to be born to a celebrity. But seriously, it requires a lot of talent, even more luck and a lot of perseverance.
