I think the reason a lot of celebrities feel insecure and want to stop eating altogether is because they see so many pictures of themselves on a daily basis. It's unhealthy how many times you see your own image - it's just constant. When you see something enough, you're going to tear it down to the point where some days you feel like you're not even pretty. I get insecure about my eyes because I once read a blog comment that said, "Her eyes are so small." I thought, Are my eyes small? Oh no - they are!

I don't want people to think of me as sexy.

I think that what people always want is what they don't have a lot of.

I would just be constantly writing all these zingers - like, 'Burn. That would really get her.' And I know people are going to obsess over who it's about, because they think they have all my relationships mapped out. But there's a reason there are not any overt call-outs in that song. My intent was not to create some gossip-fest. I wanted people to apply it to a situation where they felt betrayed in their own lives.

I think that personality traits that come through when somebody is really sincere is what makes them beautiful.

I have rules for life, but not for love. If I think too hard about a relationship, I'll talk myself out of it

You have celebrities who are pushed to the brink of a public meltdown, and so the public thinks that every person in the public eye has dirty secrets that they're keeping, or isn't what they seem, or is masking it and faking sincerity, faking authenticity, faking being surprised at award shows when you win a Grammy.

I think it's important that you know that I will never change. But I'll never stay the same either

When I was a teenager I felt like we were always being stereotyped as being really intense and dramatic and passionate and hopelessly romantic and excitable, now in retrospect I think I need to let you know those things are amazing. I hope you never lose those things.
