For the past five summers, the best tight ends from around the NFL have gathered in Nashville, Tennessee, for Tight End University -- an event hosted by the Kansas City Chiefs' Travis Kelce, the San Francisco 49ers' George Kittle and retired Pro Bowl tight end Greg Olsen.
At this year's event, Kelce's girlfriend, pop star Taylor Swift, gave guests a surprise performance.
And this time, she wasn't dancing on her own.
She took the stage at Brooklyn Bowl with country music singer Kane Brown to perform her hit song "Shake It Off" in her first live performance in six months since her Eras Tour ended.
