Wearing a sleeveless, sparkling, red and black sequined maxi dress, the 28-year-old pop star was later photographed leaving the venue, Alice Tully Hall at Lincoln Center, through a back door. She and the 27-year-old British actor later rendezvoused outside and headed home.
Swift also attended The Favourite premiere to support BFF Emma Stone, who also appears in the film. Alwyn posed for photos with the actress and other co-stars on the red carpet.
Swift and Alwyn have been dating for more than a year. They are rarely seen in public together and largely keep their relationship private. While they have yet to walk a red carpet as a couple, they do occasionally attend each other’s events while trying to avoid the cameras.
