from dailymail How to keep a model happy . . . His family’s fortune is reckoned to be £1 billion thanks to their global property portfolio, which includes 110 prime acres just north of Oxford Street in Central London. But Viscount Portman’s brother, Justin, has perhaps discovered something even more valuable — the secret of a happy marriage. According to Justin, 41, leading a separate life thousands of miles apart from his model wife Natalia Vodianova, the mother of his three children, is the way to go. Despite persistent rumours that he is on the verge of divorcing lovely Natalia, who comes from a dirt-poor Russian family, handsome Justin — who has been spending a lot of time in Uruguay putting the finishing touches to a retreat he has built at Punta del Este — tells me that is not the case. Now in Cannes, where he was helping a female choose a luxury yacht yesterday, he tells me: ‘I haven’t been in England over the summer. 'We both spend a lot of time doing different things, but it works out. We are still very much together. ‘Natalia has bought a flat in Paris as an investment, but she is still living in our house in West Sussex with the kids.’
