Some info on Mischa & James Blunt at the party:
Much-taller Mischa Barton greeted the singer by running up to him and bending down to throw her arms around his neck, squealing, "There he is!" The two shared dessert, but as she talked, says our spy, Blunt became less and less enthused. He eventually ditched Barton and moved on to Mary-Kate and Ashley Olsen. Then it was back to Mischa, who was good enough for Blunt to take to the Pink Elephant after the show. But the leggy starlet got her revenge and left him before the night was over.
