Prince William and Kate Middleton joined friends at Loulou's for a late one out in London last night. The royals spent the evening in the neighborhood of Mayfair with Pippa Middleton and Princess Eugenie. It was the end of a busy day for both William and Kate. Prince William attended the funeral of his childhood nanny, Olga Powell. Kate, though, had professional obligations. Kate toured Newcastle solo, after William had to change his plans for the sad event. Making many stops around the city, Kate met with youngsters at a community garden project, the Keyfund Office charity, and the Stockton Recovery Service. Tonight, William is expected to continue the mingling at the 100 Women in Hedge Funds dinner.
