Princess Beatrice held her mother Sarah Ferguson's hand yesterday as they left dinner at the George in London with Princess Eugenie. The girls had a fun evening out on the town to celebrate the astounding sale of Princess Beatrice's royal wedding fascinator — the Philip Treacy designed headpiece went for $130,000 in eBay, with the sum going to benefit the charity Children in Crisis. The topper caused a stir around the world and helped to make Beatrice an internationally known name. The notoriety hasn't distracted her from her studies, though, as the 22-year-old is currently finishing up her history degree from Goldsmiths College and plans to graduate this Summer. Twenty-one-year-old Eugenie, meanwhile, is working toward a diploma from Newcastle University.
