The couple was spotted at the British Vogue and Tiffany & Co. Fashion and Film Party at Annabel's Member's Club after the awards show. Alwyn looked dapper in a classic black tux and bow tie, while Swift stunned in a light blue Stella McCartney dress. The sweet duo held hands as they walked outside, with Alwyn leading Swift behind him
Swift also posted about Alwyn's big night on Instagram, celebrating the seven awards that his film, The Favourite, took home.
Back in Los Angeles, California, Swift did not win the one GRAMMY she was up for, losing the Pop Vocal Album award for Reputation to Ariana Grande's Sweetener.
The couple was last seen together at a Golden Globes after-party last month. Swift was spotted making a beeline for Alwyn the moment she entered the party, even putting her head on his shoulder and hand on his chest. Swift didn’t leave Alwyn’s side, posing for photos and chatting with Alwyn’s co-star, Nicholas Hoult, as she kept her hand around Alwyn’s waist. At the end of the evening, the two exited through the back of the venue and away from the crowds.
Earlier in the night, ET caught up with Alwyn, who revealed if he and Swift would ever work together. Watch the video below to see what he had to say:
