This reunion must have been a nightmare for Emma Roberts and Evan Peters! The former couple made a rare appearance onstage together during the Disney Upfront showcase at the North Javits Center in New York City on Wednesday, where they announced the addition of Paul Anthony Kelly to the Season 13 cast of American Horror Story. Their co-stars Sarah Paulson, Billie Lourd, Gabourey Sidibe, and Angela Bassett also joined them on stage.
