Taylor Swift brought out Gracie Abrams for a mashup of her "1989" track "Out of the Woods" and Abrams' song "Us" from her "The Secret of Us" album.

Taylor Swift was joined by her friend and supporting act Gracie Abrams during the third night of her six-show Eras Tour run at Toronto's Rogers Centre on Saturday, Nov. 16. The pair performed a surprise mashup of Swift's '1989' track 'Out of the Woods' and their collaboration 'Us' from Abrams' 'The Secret of Us' album.

Kansas City Chiefs star Travis Kelce has been in his fair share of "Eras Tour" concerts since he started dating Taylor Swift more than a year ago. As a matter of fact, the four-time All-Pro tight end attended the Indianapolis leg of the five-continent concert tour earlier this month.
