Ryan Murphy confirmed last night that Jessica Lange will appear on the second season of American Horror Story. Phew! He told terror elf Andy Cohen on Watch What Happens Live that Lange would be back in some capacity, though he did not expound on what that capacity was. Murphy also squeezed in a dig at the Glee cast during WWHL's "plead the fifth" bit: When asked who the most difficult guest star has been, Murphy paused. "You know, the guest stars are never difficult," he said pointedly. Oh, Ryan Murphy.
