Kate: I want people to know that I didn't know anyone famous, my dad didn't produce Fleetwood Mac, I definitely have somehow been blessed enough to end up where I am. I'm just a regular kid. Hopefully that translates on stage and with my fans. Some people become robots, and I don't want to be that person.
