Travis Kelce and Taylor Swift attend Tight End University event

Travis Kelce doesn't often publicly comment on his relationship with pop superstar Taylor Swift... so when he does, fans take notice. That was the case on Wednesday night, as the Kansas City Chiefs icon dived into the comments section of a picture of his girlfriend performing in Nashville.

Tight End University, the site of Swift's impromptu concert, is a multi-team collaboration aimed at helping NFL players improve their game.

Swift then got on stage at Brooklyn Bowl Nashville with an acoustic guitar to the sound of raucous cheers. She told the crowd that one thing NFL tight ends have in common with Nashville, Tennessee, musicians is that they're all friends. “We were thinking, 'How loud could this place get?'”
