She said: “I love my body. The curvier I am, the happier I am. I think that’s true of most girls. When you’ve got a lovely boyfriend you just eat cake and kiss on the sofa. It’s lovely!

“The heavier I am, the more I like my boobs and bum, and the happier I look. I’m lucky – I can eat what I want in moderation and I don’t have to exercise religiously. I’m just sensible and healthy and I never sit still for long.”

Brook, 32, admits there are some parts of her body which she would be happy to change but on the whole she is completely satisfied with her image.

She told LOOK magazine: “I could do with toning my tummy a bit more, but overall I wouldn’t change anything. I’m a stone heavier than I was in my 20s. I don’t think that’s from my lifestyle changing, it’s just from getting older.

“But I reckon I’ve got the opposite of body dysmorphia. I think I’m a size zero until I see pictures of myself and realise I’m not!”
