December 04, 2013 - 11:23 GMT hellomagazine.com Princess Beatrice mingles with Prince Harry's former girlfriend Chelsy Davy at exhibition Princess Beatrice mingled with her cousin Prince Harry's former girlfriend Chelsy Davy at a private viewing of Nikolai Von Bismarck's new photography exhibition on Tuesday night. The 25-year-old royal went for wintry chic for the exclusive evening and viewing of In Ethiopia at London's 12 Francis Street Gallery, wearing a navy blue skater skirt and black jacket. She kept warm in opaque tights and finished her outfit with a pair of black heels. She wore her auburn locks in loose waves for the evening. Beatrice was in good company, accompanied by her boyfriend Dave Clark who was handsome in jeans, a grey jumper and a long charcoal grey overcoat. The pair mingled with Harry's ex Chelsy, who was dressed in black skinny jeans, a blue top and black coat featuring a fur collar. The 28-year-old Zimbabwean was thrown a leaving party by her friends at the beginning of the year to mark her departure from the capital in favour of sunnier climes. "Chelsy is moving abroad, indefinitely," a friend told The Telegraph at the time. But Harry's former flame has since moved back to London, where she is reportedly working in a law firm. The likes of model Poppy Delevingne, Pixie Geldof, Sir Bob Geldof, Jerry Hall and Rolling Stones rocker Ronnie Wood also braved the cold weather to attend the exhibition. There was a further royal seal of approval, with Princess Maria-Olympia of Greece and Denmark and Prince Pavlos of Greece and Denmark making an appearance. The royal couple posed for a photograph with Princess Beatrice and her boyfriend Dave, with a backdrop of the photographs on show.
