Travis Kelce had a hilarious message for Gracie Abrams before his Eras Tour debut in London

Travis Kelce was not the only star who made a special appearance on stage during Swift's third night at Wembley Stadium.

The Kansas City Chiefs tight end came onstage during Swift's transition to her hit song, 'I Can Do It With A Broken Heart," from her newest album, The Tortured Poets Department. And his appearance came before Gracie Abrams, who joined Swift on stage to surprise the crowd with the live debut of her song with Swift, “Us.”

Speaking with Sirius XM, Abrams revealed what Kelce told her before the two left to take the stage. And it certainly helped calm her nerves.

“Before we both went on, we were in the tent, and he was like — he went on right before I did, like, I think two songs or something. He’s like, ‘I’ll mess up so you look really good,’” Abrams said.

And when asked about the concert as a whole, Abrams gushed about Swift.

“The thing is, is it’s just a community of really supportive people. Truly, everyone, whether you’re in the tent or in the top row in the stadium, it’s like everyone is there because there is such deep joy and feeling associated with all of the music that she’s put out over the past 18 years and it’s like, I don’t know. It’s a really magical thing,” she added.

An epic shoutout for @killatrav

After each and every one of her stops on the Eras Tour, Swift has posted numerous photos on Instagram from that state or country she was in. But for London, there was something clearly different about it.

Swift included two photos of Travis' time on stage and also posted a video one fan took of Travis taking the stage along with his entire performance beside the singer.

And she gave him a shoutout in her caption.

"And I'm still cracking up/swooning over @killatrav's Eras Tour debut 🥰," she wrote on Instagram. "Never going to forget these shows. Can't wait to do it 5 more times in August."

So both of Swift's latest posts include the tight end.

And not to mention the one with the royal family was her finally going Instagram official with the tight end. It was quite the way to do it, but only Swift could pull it off.

A mid-show surprise

Kelce arrived a little late to Taylor Swift's third and final show in Dublin, Ireland on Sunday night. And when the singer spotted him, her eyes lit up.

It was like a fairytale.

And then after the show, he couldn't hide how proud he was of her.

As the two were walking off with the fans screaming and cheering for Swift, Kelce ran a little ahead and showed just how proud he is of the singer.

He was also encouraging the crowd to cheer even louder for Swift after her three and a half hour performance.
