She said: 'We don’t live together, as has been reported recently, but we do half the time.  Everybody will stay over or we’ll all go on holiday and that’s because we genuinely want to be around each other.

'It’s great for our daughter that she has two parents who love each other and are friends. He’s definitely my best friend in the entire world.’
