Alicia Keys

I don't think even when you find a person, you can be completely honest, ever. There's still pieces of you that you don't give away. I do believe you always need that place where it's just you, your thoughts, no one else's judgment or anything.

Adam Levine and I remade the Rolling Stones' classic Wild Horses, and it is right up my alley, that whole style. It has a style of its own but still stays very true to the classic arrangement, and I love it.

I'm not likely to be attracted to characters I've already done. I have to be almost frightened by the possibility of taking it on. Over the years, I realise I must enjoy walking that edge; I keep doing it.
