Anna Paquin and Stephen Moyer were arm in arm at the premiere of True Blood last night in Hollywood, joining their costar Alexander Skarsgard for the big debut. The onscreen vampires may be part of a love triangle on the HBO hit, but off screen, the trio are close friends. Stephen recently said he thinks the romance heating up between Anna's Sookie and Alexander's Eric will be a good thing for the series, but he personally chooses not to watch his wife tape love scenes with Alex. Stephen is on the cover of Men's Health's new issue, in which he opened up about falling in love with Anna during the show's first months by sometimes Skyping for two or three hours a night! Alexander, Anna, and Stephen's many costars were also on hand to toast the program and its success. Werewolf Joe Manganiello looked rugged in red, and Ryan Kwanten, Nelsan Ellis, and Todd Lowe rounded out the cute guys on the carpet. Meanwhile, Evan Rachel Wood debuted a bold, cropped hairstyle, Deborah Ann Woll looked lovely in a lace gown by Tadashi Shoji, and Rutina Wesley glowed in a simple, beaded dress. The countdown is on for fans of the drama — True Blood season four debuts on this Sunday, June 26!
