Help me please!!!!!!?

well it's always been my dream to be famous. I want to be the next Hilary Duff and I'm deadset on doing it. I want a really cool stage name. My name in real life is Katie and my last name starts with a T. I'm cute, stylish. In looks, people often compare me to Jamie Lynn Spears. Please give me some ideas on stage names!!?!?! THANKS.
