'Bellyache' is totally fictional. I like writing about things that aren't real. The song is about not trusting anyone and then putting trust in yourself and realizing that you don't know what you are doing, either. Or realizing that things you do with a group of people that you think are cool in the moment are ultimately all on you.
I'm a really artistic person, and so, with the live stuff, there's a lot that I think is really cool. Beyonce and Rihanna have all these dancers. So with the live costumes and video costumes, I'd really like to have my vision. The way that I want people to dress is very specific. I love fashion.
