Now that's what we call "classic." Taylor Swift is notorious for bringing tons of different artists up on stage with her during her tours — including her "Bad Blood" music video co-stars! Most recently though? TayTay brought out MKTO, one of our favorite musical duos of all time!
"Thank you @TaylorSwift for being so classic and allowing us to perform with you tonight @GilletteStadium! We love you!" the boys captioned the above pic of their performance together.
Are you excited that MKTO performed with Taylor on stage? Who do you think she'll surprise her audience with next? Comment your thoughts below!
