The Duchess of York, 63, proved that she can still party with the best of them as she was spotted finishing a night out on the town at 2am.The Royal - born Sarah Ferguson and nicknamed 'Fergie' - was joined by her daughter Princess Beatrice at a central London soiree, which ended the mother-daughter duo being photographed swanning out of a private members' establishment in the early hours of Thursday morning.The pair had seemingly relished a night away from royal responsibilities in the popular Mark's Club in Mayfair, a venue which in the past has hosted many fashion events and counts many members of the British establishment as patrons. Styling her signature auburn locks in a trendy half-up-half-down do, Fergie - former wife of Prince Andrew - donned a sophisticated button down turquoise tweed dress, which she paired with a simple black beaded clutch bag and gold jewellery.
