The knockout performance in question happened at the Tight Ends and Friends concert at Music City's Brooklyn Bowl, with Swift getting the crowd hyped up as she took the stage in a black dress and matching heeled boots. As she strummed her guitar, Brown danced along on stage and added extra percussion by shaking a stick of bells.

Taylor Swift and Travis Kelce have been enjoying some "rare" downtime which has allowed their "bond to deepen," a source tells PEOPLE. This summer has been a "turning point" for the couple, who began dating in 2023.

Kelce concluded his 2024 NFL season when the Chiefs fell to the Eagles in the Super Bowl in February after Swift wrapped up her Eras Tour a few months earlier in December, which has made the past few months some of the first time the couple has had to themselves.
