Music is art, and art is important and rare. Important, rare things are valuable. Valuable things should be paid for.

Where is the video of Kanye [West] telling me he was going to call me 'that b***h' in his song? It doesn't exist because it never happened. You don't get to control someone's emotional response to being called 'that b***h' in front of the entire world.

The only thing I can't control is the spin in the press. And so if I know I can't control that, I have to let it go.

Forgetting someone is like getting over a hundred addictions everyday.

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.

Some combinations of people are toxic, you know? You have to find the right one that isn't just going to explode into fiery ash and destruction.

I've never been fascinated by the party lifestyle. Penciling in a night to get wasted is not something I want to do.
