The low-key couple turned away from the cameras as they headed home for the night, but held each other tight. Swift, 27, covered up in a colorful coat and black combat boots, while her beau, 26, looked casual in a dark jacket and jeans.
The GRAMMY winner performed "End Game" with her pal, Ed Sheeran at Friday's concert, and while he didn't join the couple after the show, he's a big fan of Alwyn.
"He's really nice. Really, really friendly, really good dude," Sheeran said of the British actor in an interview with Roman Kemp on Capital Breakfast in October. "[Swift and I are] in touch, quite a fair bit, you know, and she's been in London quite a bit as well."
