AHS creator Ryan Murphy tweeted a photo of conjoined twins from their first day on set of the new season, which is set in a 1950s Florida freak show.
Sarah Paulson actually plays both twins "using a mix of practical physical effects make-up and CGI." She tweeted a digital mockup of her characters last month, but yesterday was her first day on set in makeup.
Jessica Lange is also returning to the show as the manager of the touring freak show. Evan Peters, Frances Conroy, Kathy Bates, Emma Roberts, Gabourey Sidibe and Angela Bassett will also be back for upcoming season.
