What are you wearing right now?
A Diane von Furstenberg fitted, grey wool polo-neck jumper and grey leggings, and buckle sheepskin boots from the Celtic Sheepskin Company.
Who's your style icon?
I don't have one person, but I love the way Sharon Stone looks – always fabulous but without looking like she has tried too hard. I think Dannii Minogue has really found her style too. It's not to do with fashion but to do with people being confident in their 'look'.
What can't you live without?
My shoes. I have far too many but I love them all! When we were little we had our best pair and our school shoes, and that was all. So now that I've got the opportunity to have more, I grab it.
Describe the best outfit you have ever worn.
I suppose everyone talks about my red dress from the final of 'Britain's Got Talent'. It was fabulous – real, old-school, Hollywood glamour. In the fitting we took it in an inch, not taking into account that I would actually have to sit down in it. So I spent the whole of the final perched rather uncomfortably on the edge of my seat!
What's in your wardrobe?
What is in your make-up bag?
At the moment I'm using Avon mascara, Bobbi Brown cream blusher, and MAC eyeliner in black and brown. I also have the Stila lip glaze – an instant make-up boost.
What's in your handbag?
Christopher, my husband, has just bought me a handbag from Louis Vuitton – bright red! In it is a diary, a camera, some jelly snakes from the Natural Confectionery Company (my new fad). Ariane Poole secret highlighter, my keys and a bottle opener I inadvertently nicked from a hotel.
If you could live in any decade, style-wise which would it be?
The Forties or Fifties – the clothes were so feminine and flattering and structured. A couple of years ago I did '4.50 from Paddington', a Miss Marple TV film, and the costumes were lovely. I could barely breathe, but it was worth it!
How often do you look in the mirror?
If I'm in the bathroom I'll have a look in the mirror, or if I pass a shop window I'll always check out what I look like. Or if I'm in the car perhaps too. But I don't think I'm always obsessively peering into mirrors all the time!
What's your secret style tip?
I swear by Armani foundation. It's so fine it's almost like airbrushing and leaves you with a flawless finish.
