It is unseemly to undress on stage. I won't do that.

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.

I'm a fiend for costume jewellery and have countless pairs of rhinestone or diamante earrings, which are so flattering when they catch the light. I love the designers Alexis Bittar and Kenneth Jay Lane, and I always go to jewellers Butler & Wilson.

And then I wrote my first autobiography when I - well, it was 23 years ago. And since then I've written about one book every two years.

However much some journalists may criticize me, I know that I look, feel, and behave several decades younger than my actual age, and much of that is because I believe you are what you think you are. This is called positive affirmation, and it's a really strong tool.

Most of the time we've been living in England and now we've bought an apartment in New York which we absolutely love.

And sometimes when I would get in the morning, when we'd go out - we'd see shrapnel and bits of stuff in the streets and bombed buildings, and - but I was evacuated a lot. Every time the blitz got heavy, my parents would take us off to the country.
