Taylor performed at New York City's Jingle Ball on Friday, before jetting off to London to also perform at the Capital FM Jingle Bell Ball on Sunday.
After performing some hit songs like "Ready For It," "Look What You Made Me Do," and even "Blank Space," Entertainment Tonight reports that Taylor made her way to the crowd to find Joe, while they watched her bestie Ed Sheeran perform.
And of course, Taylor and Joe got completely lovey while Ed sang his hit new single, "Perfect."
One eagle-eyed fan got some footage of the pair showing off some major PDA, arms wrapped around one another and continuously kissing.
"THEY LITERALLY SLOW DANCED TO ALL EDS SONGS WITH THEIR ARMS AROUND ONE ANOTHER AND JUST KEPT LOOKING AT EACH OTHER AND KISSING," the fan wrote excitedly on Twitter.
We couldn't be happier for Taylor and her newfound LOVE!
