Taylor Swift is joined on stage by Travis Kelce, during

Taylor Swift certainly seems to be enjoying her time in London.

During her third night performing for a crowd of 90,000 people—including several British celebrities—at Wembley Stadium, and her 106th Eras Tour show globally, the singer found a unique way to surprise her fans and the internet: with a special appearance—and performance—from her boyfriend Travis Kelce.

Kelce, tight end for the Kansas City Chiefs, made an onstage appearance during the introduction to Swift’s Tortured Poets Department song “I Can Do It With a Broken Heart.”

Videos of the viral moment showed Kelce sporting a tailcoat and top hat to match the attire for the scene, in which Swift is urged along with her costume change to continue performing.

As part of the act, Kelce lifted Swift to a couch, fanned her and even powdered her face, before waving her on to do the song. Before singing, Swift turned to Kelce and blew him a kiss.

Social media users were amazed by the revelation. “Travis Kelce has made history. Carrying the Lombardi Trophy and the music industry in the same year,” wrote one user. And “there is something extremely poetic about travis kelce carrying taylor swift away after her heart was shattered….” wrote another.

Swift and Kelce were first romantically linked last September, a few months after Swift’s rumored split with the 1975 frontman Matty Healy—who is speculated to be the inspiration for the song—and several months after her official breakup with longtime beau Joe Alwyn.

“I Can Do It With a Broken Heart” speaks to the experience of performing through heartbreak and masking misery. However, it’s safe to say that Swift is no longer doing her shows with a broken heart.

In Buenos Aires, during the Eras Tour, Swift changed the lyrics of her song “Karma” to reference “the guy on the Chiefs coming straight home to me.” And Kelce has been spotted at Swift’s concerts around the world, typically dancing among the audience.

As Kelce found himself on the stage on Sunday, a number of other stars were among the spectators—including Paul McCartney, who was spotted exchanging friendship bracelets with Swifties. Swift’s previous two nights at Wembley were attended by, among others, Love Actually actor Hugh Grant—who described Kelce as “excellent if gigantic” in a post praising Swift—and Prince William, who shared a selfie taken with Swift and his children Prince George and Princess Charlotte. (Swift revealed that Kelce also met backstage with the British royal family.)

Swift is headed to Dublin, Ireland, next and then to other parts of Europe through the summer, though she’s returning to London in August for five more shows at Wembley before the Eras Tour goes back to North America for the fall.
