Taylor Swift caused a stir among fans when she made a notable change to her song “Fifteen” during her Eras tour show in Singapore on Thursday, March 7, coincidentally the same night her boyfriend Travis Kelce arrived on the island.

The Grammy-winning artist, aged 34, omitted a key lyric from the song, “Well, in your life you’ll do things / Greater than dating the boy on the football team / I didn’t know it at 15,” while performing a piano rendition of the track, merging it with “You’re on Your Own, Kid.” This alteration occurred during her second segment of surprise songs of the night, as captured in fan footage shared on TikTok.

“Fifteen,” a nostalgic reflection on youth and love, was originally featured on her debut album Fearless in 2008. Swift sang the beginning of the song before transitioning into “YOYOK,” leaving out the football-related line which typically appears towards the end of the track.

Swifties, as her fans are affectionately known, couldn’t help but speculate about the significance of this change, particularly given Swift’s relationship with three-time Super Bowl champion Travis Kelce, also 34, since August 2023. Various theories surfaced on social media platforms.

“Taylor performing Fifteen but not singing the line about dating the boy on the football team… criminal,” remarked one person on X, expressing disappointment over the omission. Another echoed the sentiment, stating, “How do we feel about Taylor skipping the line ‘in your life you’ll do things greater than dating the boy on the football team’ during fifteen x yoyok mashup………….. I don’t feel well.”

However, another interpretation emerged, suggesting a subtle nod to Swift’s high school best friend, Abigail Anderson, who inspired the song.

“Fifteen x YOYOK: Travis was the guy on the football team who broke Abigail’s heart in hs and now Taylor is carrying out their 20 yr revenge plot to destrooooy him,” speculated a user.

The implications of Taylor playing Fifteen, skipping the ‘in your life you’ll do things greater than dating the boy on the football team’ and then mashing it up with yoyok and keeping the friendship bracelet line in…” pondered another.

During the performance, Taylor sang the full version of “You’re on Your Own Kid,” a track from her 2022 album Midnights, including the lines, “So make the friendship bracelets / Take the moment and taste it / You’ve got no reason to be afraid.”

Travis famously attempted to meet Taylor at one of her Eras tour shows in Kansas City in July 2023, presenting her with a friendship bracelet bearing his phone number. Although he was unable to hand it to her personally, his admission of being “butt hurt” on his “New Heights” podcast caught Taylor’s attention, leading to their eventual connection and the beginning of their romance.

The couple is soon to be reunited after Travis experienced an emotional week in the U.S., marked by his older brother Jason Kelce’s retirement announcement from the NFL after 13 seasons on March 4. Travis, who attended the emotional press conference, later joined his brother in their hometown of Cleveland for a special Kelce Brothers bobblehead night hosted by the Cavaliers. Subsequently, Travis and his entourage embarked on a journey to Singapore via Dubai.

Several of Travis’ friends shared updates from Singapore, including Henry Clark, who provided a panoramic view from their suite at the renowned Marina Bay Sands resort. Although they missed Taylor’s Eras tour show on the fourth night in Singapore, there are still upcoming performances on March 8 and 9, where Travis and his friends can support his girlfriend.
