Curvy model Kelly Brook knows her buttocks don't compare to Pippa's

Kelly Brook openly admits that her bum is not as impressive as Pippa Middleton‘s.

The model and TV star came to the conclusion at her best friend’s recent wedding.

‘I was chief bridesmaid and I was channelling Pippa Middleton all day but my bum apparently didn’t look as good as hers,’ says Kelly, 31.

‘I had a floaty dress on so I didn’t have the right outfit for the bum she had.’

Kelly has been busy getting back in shape after suffering a losing the daughter she was expecting in May.

‘I’ve been working out, riding my bike, going back to the gym and doing photoshoots and modelling,’ she tells The Sun.

‘It’s been really nice to get back in my body and get fit again.’
