On Tuesday, June 24, the pop superstar, 35, gave a surprise performance at her boyfriend Travis Kelce’s Tight Ends & Friends concert at the Brooklyn Bowl in Nashville.

“We would like to dedicate this to our favorite players who are going to play and these are the tight ends,” Swift, who wore a black mini dress and matching boots, said as she introduced the song while referencing its lyrics.

“I stay out too late,” she then began singing as the crowd went wild.
