I've made no secret of the fact that I often wear wigs and have in fact launched my own Dynasty range, named after various characters. I find this saves a ton of time - as well as my own hair.

I'm extremely happy in my life. I consider myself to be very blessed.

Certainly there are dozens of over-50 actresses who look great: Sophia Loren, Susan Sarandon, Ursula Andress, Stefanie Powers, Raquel Welch, Barbara Eden, Joanna Lumley, Linda Gray - the list is endless, and these are just the actresses! I have many friends in their 60s, 70s and 80s, not in the limelight, but who all look absolutely stunning.

I was thinking, who of the English actresses in the last 30 or 40 years have achieved as much as I have?

Of course it does on opening night, but I've never had that devastating stage fright that some people get, but apparently, you can develop it.

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.

From the age of 17 I was a pin-up girl. I did it for 30 years and, quite frankly, it gets a bit boring.
