Taylor Swift fans are abuzz with excitement after they believe the pop superstar made a subtle yet touching change to the lyrics of one of her songs during a recent concert, seemingly as a nod to her boyfriend, NFL player Travis Kelce.

The 35-year-old “Fortnite” songstress, who has been dating the Kansas City Chiefs tight end since last summer, ended the European leg of her Eras Tour with a record-breaking show at London’s Wembley Stadium on Tuesday night.

In front of a massive crowd of 92,000 fans, Swift delivered a performance full of surprises, including a rendition of “So Long London” from her latest album The Tortured Poet’s Department.

The song, which was included as a special surprise for her British fans, seemed to have an extra layer of meaning for the star as she bid farewell to the British capital.

Swifties, as her devoted fans are known, quickly picked up on what they believe was a change in the song’s final lyric. Instead of singing the original line, “You’ll find someone,” Swift reportedly altered it to “I’ll find someone.” Fans immediately speculated that the change was a reference to her relationship with Kelce, with whom she is expected to reunite as she returns to the United States while he prepares for the upcoming NFL season.

Social media lit up with reactions to the perceived lyric change, with many fans convinced it was a heartfelt gesture towards Kelce. “So long London, I found someone,” one fan posted, sharing a photo of Kelce performing his signature Archer touchdown celebration alongside an image of Swift mimicking the pose during one of her concerts.

Another fan echoed the sentiment, writing, “The final line in ‘So Long London’ is ‘I’ll find someone’ and she did,” adding a stream of heart emojis to express their joy. “So long London, I found someone—she sure did,” a third Swifty enthusiastically agreed.

Fans also recalled that this isn’t the first time Swift has adjusted her lyrics to honor Kelce. Last November, after weeks of supporting her NFL beau during games, Swift made a memorable change to the lyrics of her finale song “Karma” during a concert in Buenos Aires, Argentina. In that performance, she sang, “Karma is the guy on the Chiefs,” in a sweet nod to Kelce, who had traveled to South America during the Chiefs’ bye week to support her.

This lyric switch has since become a tradition whenever Kelce is in the audience for one of her shows, akin to a royal standard being flown when a monarch is home, as one amused social media user pointed out.

As Taylor Swift prepares to reunite with Travis Kelce across the Atlantic, her fans are left speculating about the meaning behind these lyrical changes and what they might signal about the couple’s future. One thing is certain: Swifties will be keeping a close ear on her performances for any more romantic nods to her NFL star boyfriend.
