Taylor Swift is excited about Travis Kelce’s appearance on her tour.

Couples who play sold-out stadiums together, stay together. This was evident at Taylor Swift’s Eras Tour concert in London where Travis Kelce surprised the crowd at Wembley Stadium by appearing on stage during his superstar girlfriend’s The Tortured Poets Department set. In a new Instagram post, Swift revealed that she still has heart eyes because of it, sharing photos of Kelce joining her under the spotlight, including one of him carrying her in his arms, looking dapper in a tuxedo and top hat. In the caption, Swift wrote, “I’m still cracking up/swooning over @killatrav’s Eras Tour debut 🥰.”

The “Anti-Hero” singer also posted a video of Kelce’s full appearance, where he playfully forces her to perform “I Can Do It With a Broken Heart” even after she dramatically collapsed following “The Smallest Man Who Ever Lived.” In the clip, Kelce picks her up, carries her to a couch, fans her, and dusts her face with a makeup brush while coaching her on singing and dancing for the next number.

But Kelce’s hilarious performance was just one of the surprises at Swift’s trio of London shows. At one point, opener Hayley Williams joined the Grammy winner on stage for an acoustic performance of their duet “Castles Crumbling,” and Grace Abrams later sang their collaboration “Us.”

“Acoustic sections went OFF,” Swift continued in her post. “I got to sing ‘Castles Crumbling’ with @yelyahwilliams for the first time – hadn’t performed with her since 2011 and man, my heart was just so full of love for her and our friendship. Then the talented @gracieabrams surprised the crowd with the first performance of our song ‘us.'”

Next, Swift will perform three nights in Dublin, followed by shows in Amsterdam, Milan, and other European cities before closing out the leg with five more nights in London in August. In October, she will start the final leg of the Eras Tour in the U.S. and Canada. Swift expressed her gratitude for the surreal experience of performing at Wembley Stadium, looking out at crowds of 90,000 fans each night and hearing their enthusiastic cheers. She mentioned that those were some of the loudest crowds she had ever encountered and that she would never forget these shows.
