I always say as a celebrity you have two choices - you can be a celebrity, or you can be a role model. You can choose to just go to parties and do the red carpets and all that, or you can choose to be an example to these people.

It has taken me a long time to work out the function of ex-boyfriends, at least for me: how they can help you work out what you want from life and from a partner by showing you what you don't. If a man is your ex, it's better all round if he was not Mr. Right.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
