I don't know why people are so obsessed with age anyway. I mean, 90 is the new 70 70 is the new 50 and 50 is the new 40 so the whole act-your-age thing? Only up to a point.

I'm a woman for all seasons. I mix 'n' match, do designer and high street - keep all my good pieces. I design all my evening and cocktail dresses most of the time as I dislike what is out there.

Hair, in fact, is probably the bane of most women's lives.

I was voted the most beautiful girl in the world in 1958, and courted by every young, available man in Los Angeles, most of whom I didn't go out with, by the way.

I never thought I was particularly good looking. But when I see old photographs, I realise that I was. I do wish I had known that at the time because beauty is power. I didn't realise how lucky I was to be young, beautiful and in Hollywood. It didn't hit me. Every day I woke up, went to the film studio and just got on with it.

I blame my grandmother for encouraging me to become an actress.

If you feel well and happy, your face will reflect this, but if you are down in the dumps and having a miserable time, your face will soon show this, too. In fact, you get the face you deserve by the time you're forty, and one of the keys to looking and feeling younger is being active.
