The premiere for the new season of American Horror Story took place tonight in Los Angeles. Lady Gaga, who plays The Countess in the show, premiering Oct. 7 on FX, was the last one to arrive. She looked absolutely stunning while wearing a red gown designed by Brandon Maxwell (check out our Fashion section here) and posing with Taylor Kinney, Ryan Murphy and the rest of the cast for the photographers. Once inside, she joined Ryan Murphy, who introduced her to the public previously, on stage. Photos and videos from the night are available below!
