Taylor Swift joined Travis Kelce for the kick-off of Tight End University in Nashville earlier this week and took the opportunity to perform her song “Shake It Off.” During the opening night’s afterparty at Nashville’s Brooklyn Bowl, singer delivered a surprise acoustic performance of the 2014 track for NFL players and guests.

"There are Monday fun days, and then there are Monday fun days when Taylor Swift is in the building partying to your set," DJ Mike Fresh wrote on Instagram.

Taylor Swift, who officially lives in Nashville, was supporting Travis Kelce as he cohosts the annual Tight End University in the city.
