You used to be a nail technician? Do you still keep your hand in?
I used to give manicures to the residents my parents look after in their care home in Blackpool, but I don't have time now. I can't even really wear acrylics myself any more because I have to have grubby nails with dirt under them for the show – although sometimes I can't resist and I have just found an amazing little nail shop on Tottenham Court Road in London's West End where I had a full set of acrylics done for £20 and that included a touch of nail art on one of my thumbnails. When I'm not working, I wear dark colours which look best with short nails - Dior Vernis Long Wearing Nail Lacquer in Mystic Violine, £14, a gorgeous deep-purple and Bourjois So Laque polish in Bleu Mysterieux, £5.37, the most amazing deep-blue.
Do you spend a lot of money on cosmetics?
No, I love a bargain. I've brought all my hair products down to London from home in Blackpool because I usually get them from the pound shop. I don’t even know what mousse I use because all the writing on the can is in Indian. It was a pound! I've still got ten bottles of it that'll last me the rest of my life.
Is that how you get so much movement in your hair?
My hair is poker straight - there's not a kink in it – so I sleep in sponge rollers underneath a pair of tights. Lovely sight. It works, though. That's my key to looking good - cheap mousse and going to bed with your rollers in and your tights wrapped round your head. Boots Essentials Bendy Rollers, £5.60 for eight.
Do you have a signature scent?
There are two sides to me that I like to reflect with my perfume: I love Dior J'Adore, £38 for 30ml eau de parfum because I'm a real romantic, but also Coco Chanel, £39 for 35ml eau de parfum, because it's a scent for strong women.
How do you feel about cosmetic surgery?
My feeling is it's the imperfections that make you the person you are - if I didn't have my laughter lines, I wouldn't know I'd laughed half my life. But Chanel Teint Innocence Foundation, £25, which was recommended to me by a make-up artist at the BBC, does improve the look of my skin, giving it a luminous sheen.
