I was never particularly wild, just very busy and often didn't think about what I was putting into my body. Today things are very different. I stopped smoking in my late 30s; I avoid wheat and gluten as this makes me feel bloated and sluggish; exercise regularly and bounce out of bed.

My father had his own business, a clothing store, which he inherited from his father. He travelled abroad frequently and was quite extravagant, so we had skiing holidays and summer holidays on the beach.

I tried the Atkins diet in the Seventies when pregnant with my son, as I didn't want to pile on the pounds. Now, so long as I'm healthy, I don't care what my scales say.

I'm not scared of snakes, spiders or heights. I have three children; as a mum, you can't be afraid of things like that.

As for the stage fright, it never goes away. When I'm waiting in the wings to go on, it's agony every single time but I stay focused and I know that once I'm on stage it'll be fine; I'll be in my happy little bubble.

I was brought up very conservatively. My father was positively Victorian - I wasn't even allowed to wear my hair down.

I'd rather kill myself than dress like Victoria Beckham in towering heels day after day.
