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.

Taking the stage at the concert, which is a part of Tight End University — the annual three-day summer training camp Kelce founded in 2021 with fellow NFL star George Kittle and sportscaster Greg Olsen — Swift performed her 2014 hit “Shake it Off.”

“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.

Speaking about the surprise moment, an exclusive source told PEOPLE, “Taylor surprised the crowd by joining Kane Brown onstage for ‘Shake It Off.’ The crowd lost their minds! At the end of her performance she made sure to thank the band and gave each one of them a hug.”

The source added that Swift and Kelce, 35, arrived at Tuesday’s event together in a black SUV.

Her surprise performance comes after she and Kelce made what fans were calling their “red carpet” debut at the Tight End University’s opening night ceremony on June 23.

A video posted by the Tight End University Instagram page shows the couple beaming as they walk a red carpet into the event while hand-in-hand.

According to the event’s website, the camp was founded to help tight ends “bond, collaborate with, and learn amongst their peers while participating in a variety of activities including film study, on-field drills, recovery, rehabilitation, and more.”
