For the world's most devout Swifties, Christmas has come early — Dec. 10, to be exact.

Taylor Swift and boyfriend Joe Alwyn, who've been dating in the shadows for months, let their romance shine brightly at the Capital FM Jingle Bell Ball in London to cap off the weekend, and packed on the PDA in front of a crowd full of fans who cheered them on.

After Swift performed at the show — and during a set performed by her pal Ed Sheeran — the singer eventually found Alwyn in the crowd and wrapped her arms around him. The couple slow danced as Sheeran crooned and eventually kissed.

“THEY LITERALLY SLOW DANCED TO ALL EDS SONGS WITH THEIR ARMS AROUND ONE ANOTHER AND JUST KEPT LOOKING AT EACH OTHER AND KISSING,” one observer wrote on Twitter, while another noted “TAYLOR AND JOE ARE SWAYING WITH HER HEAD IN HIS F------ SHOULDER KISSING TO PERFECT I GOTTA...LEAVE THE ARENA.
