Taylor Swift showed up in a big way for boyfriend Travis Kelce on Tuesday night.
The 35-year-old popstar hopped on stage and put on a surprise performance for guests attending Kelce's Tight End and Friends concert in Nashville.
Singer Kane Brown, who performed a duet with Swift at the event, had the best reaction to her impromptu performance.
"When you think you're the special guest BUT you're not," Brown posted on Instagram early Wednesday morning, alongside a photo of Travis and Taylor.
In the happy photo, Kane, 31, wore a casual white T-shirt paired with a matching hat and camouflage pants.
At the same time, Kelce donned a matching two-piece camo outfit, while Swift rocked a slinky black dress and knee-high boots.
Swift borrowed another singer's guitar to perform 'Shake It Off' with Kane Brown
After Brown introduced Swift as a surprise guest at the concert, the "Fortnight" singer took the stage and asked the crowd, "Theoretically, how loud can we get?"
She then wowed the audience with an acoustic performance of her hit song "Shake It Off."
At the end of the song, Swift, who has been dating Kelce since 2023, told the audience, "We decided we were gonna perform that three minutes ago."
It was also revealed that she didn't have a guitar on hand to perform, so singer Chase Rice, who also performed at the event, loaned her his.
Kelce, along with San Francisco 49ers star George Kittle and retired Charlotte Panthers star Greg Olsen, founded Tight End University in 2021.
This is the fifth year of the NFL stars' event, which draws 80-90 tight ends to Nashville to raise money for charity.
