It was her first "Eras" tour surprise song of the night, and Tay teased it saying, “Every single time I have an acoustic set, I’m always trying to think of things you might want to hear — maybe things that might be a little bit unexpected. Let's see how we did tonight."
Swifties went crazy for the tune, which was performed as a mashup with her hit "Evermore" album song "Gold Rush."
As fans know, TS wrote “This Is What You Came For” with then-boyfriend Harris.
TMZ broke the story ... Taylor wrote the tune, but used the pseudonym Nils Sjöberg.
She and Harris agreed it was a bad idea to let the world know they collabed as a couple because it would overshadow the song.
Swift previously performed the hit in October 2016 at the Formula 1 Grand Prix, and again at a performance in 2017.
Swift and Harris dated for just over a year between 2015 and 2016.
