Bethann Hardison has been my collaborator, my closest friend, we've gone through starting businesses, losing businesses, kids, divorces, marriages, and she was my maid of honor when I married my husband, David Bowie. And she's still such a part of my life. This is the person when it's totally dark, outside and inside, this is the person I would call.

The one thing you learn as you get older is that the body will do what the body wants. All you can do is try to guide it a little.

Your image as a model is your currency. That's the only thing you've got. No one cares what you look like in real life. Nobody is going to say the make up guy was terrible. They will say, you look awful and let's not book her again.

One thing my mother always instilled in me is to always know my worth. Don't settle for less. She used to say to me 'Iman, no is a complete sentence, learn to say no. You don't have to explain it you don't have to say anything after it. It's a complete sentence.' So when I came to America 1975, I found out that the black models were being paid less than white models. So the first thing I did was say I'm not going to do the job unless I'm paid the same amount.

The one thing I know for a fact - some days are bad, some days are okay, and I'll go with it. If it's bad, I stay in and ride the wave and somehow, God gets me through and I'm fine. Dealing with grief doesn't work from one person to the other, it's so personal.

The child must come first above all else. And pace yourself every day. There is quite a lot you will have to give up.

My saving grace was that I always knew when to leave the party.
