I am the excuse to explore your identity. To be exactly who you are and to feel unafraid. To not judge yourself, to not hate yourself.

I know people said I wasn't selling out in America, but that was entirely untrue. We sold out all over the world, and every night I looked out into the fans and those front rows that you're talking about, the tears, the honesty, the inability to not be completely overjoyed because they felt accepted.

I would rather die than have my fans see me without a pair of heels on. And that's show business.

Every video I'm in, every magazine cover, they stretch you - they make you perfect. It's not real life. I'm gonna say this about girls: The dieting wars have got to stop. Everyone just knock it off. Because at the end of the day, it's affecting kids your age. And it's making girls sick.

I like pushing boundaries.

The last thing a young woman needs is another picture of a sexy pop star writhing in sand, covered in grease, touching herself.

In case you're wondering whether I lip synch, the answer is no... people think so because I sound so good.
