Kelly Brook stays slim by romping with boyfriend Danny Cipriani.
The 32E glamour model, who is a curvy size 8, burns calories between the sheets by bedding the rugby hunk.
‘Sex keeps me fit and healthy,’ she tells The Sun. ‘What can be better than that?
'I keep my figure by eating what I want – but not in bulk.’
Kelly, 28, started dating Danny, 21, last summer, shortly after splitting from actor Billy Zane, 42.
