Princess Beatrice stepped out of the Kensington Roof Gardens nightclub in London on Friday. The private space is owned by Virgin, the company that Beatrice's boyfriend, Dave Clark, works for, and is one of the many glamorous destinations that the princess and Dave frequent. The duo were spotted having dinner at Nobu earlier this month following the exciting royal wedding. Beatrice turned heads with her outfit at the event, and her Philip Treacy fascinator got so much attention that she's now auctioning it off on eBay with the proceeds going to UNICEF and Children in Crisis. The bidding is already up to about $26,100, but the Princess Beatrice hat auction will be open until May 22.
