"Game of Thrones" stars Sophie Turner and Maisie Williams are best friends. Turner said that she and Williams always have sleepovers when they are in the same town. While at New York Comic Con on Saturday, Turner revealed what they'd do during the evenings: get high and sit in the bath. "We're kind of like loners on 'Game of Thrones,' just because the past few seasons Maisie and I have sleepovers every night when we're shooting or every night whenever both of us are in town," she said.
