Which beauty products do you swear by?
I always moisturise with vitamin E cream, usually from Boots.
I also use liquid eyeliner and some mascara if I’m going out.
Do you have a bursting cosmetics bag?
Not any more.
When I was in my twenties I had hundreds of items of make-up, but as I’ve got older I’m now just down to the basics.
What are your top tips for looking good?
I haven’t drunk alcohol since Christmas, for no other reason than I wanted some time off from it, and I’ve noticed a massive difference in how my skin looks.
I don’t get dry skin any more.
How do you freshen up after a day on set?
Even though my character [Jeanne]doesn’t use much make-up, I constantly have dirt and things on my face so it’s great when they remove it all.
The best thing is the spray of cooling water afterwards.
Do you wear make-up every day?
No, I don’t. When I was younger I used to spend so much time panicking about looking good but now I just use make-up for fun.
Do you diet?
Usually after Christmas, I try and lose the half-stone I’ve gained but I don’t believe in denying yourself anything.
I just think, “I’ll cut out the bad stuff for a bit”.
How do you stay in shape?
My youngest child is only three and isn’t at school yet, so I don’t have time for the gym, but I cycle and swim when I can.
And my husband [Rupert Hill] and I are planning to climb Snowdon for his 40th.
What is your signature fragrance?
Coco Mademoiselle by Chanel, and in the summertime I use Jo Malone Wild Fig & Cassis.
How do you pamper yourself?
I don’t go in for full treatments but I love a good massage. It’s my favourite thing for winding down.
Do you have a favourite shop or designer?
I’m a high street girl. I really like Zara, Next and Topshop
Who is your style icon?
She’s really cool and when she’s on the red carpet she can be really glamorous without it looking like a massive effort.
