Do you take any vitamins or supplements? I want to do this thing called Dr Natura. It's from America and it's a colon-cleansing treatment. They send you a pack and you take two tablets in the morning, you mix a drink from a powder and then, in the evening, half an hour before you go to bed, you have this special tea. You just lose everything and it's all completely natural. My boyfriend is doing it at the moment. So, no, I don't do any vitamins, but I am trying to flush out my colon.

Do you prefer healthy food or fast food? Healthy food. I lived on such crap for years, I was very much a meat-and-potato girl. But when I got to about 20 my taste buds changed and I just went, "Oh I really fancy a salad." I don't know why.

Have you ever dieted? If I ate everything I wanted to eat, then I wouldn't be the size I am.

What foods do you have in your shopping trolley? HP Sauce. Always a bag of lettuce. Chicken. I am a big fan of crisps, and pasta, always pasta in my shopping trolley.

Do you drink alcohol? That's my vice. I used to drink about four or five times a week. But the older I get, the less I drink - I am trying now to drink just once a week, if that, because I feel much better when I don't.
