I don't believe in dieting.

I never think about age. I believe your age is totally how you feel. I've seen women of thirty-five who are old and people of seventy-five who are young. As long as I look after myself physically, mentally and emotionally, I'll stay young.

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.

Isn't three quarters of life a guilty pleasure?

When I was 49, I posed for Playboy - I was very flattered to be asked. I was quite honoured, really, considering that most of the models they feature are in their twenties.

I was so fortunate to work closely with the designer Nolan Miller whilst on 'Dynasty' to create the wardrobe for Alexis Carrington Colby, and we had great fun sourcing outfits.

We live in a quick-fix society where we need instant gratification for everything. Too fat? Get lipo-sucked. Stringy hair? Glue on extensions. Wrinkles and lines? Head to the beauty shop for a pot of the latest miracle skin stuff. It's all a beautiful £1 billion con foisted upon insecure women by canny cosmetic conglomerates.
