BUENOS AIRES, ARGENTINA: Taylor Swift's ardent fans are now discussing the possibility that the singer may have thrown in another nod to Travis Kelce during her Buenos Aires concert on November 11, besides the already-celebrated alteration of 'Karma' lyrics.

Fans believe the pop sensation may have delivered another sly shoutout to her new beau during a surprise song segment, adding a new layer to their budding romance.

Taylor Swift's subtle romance nod in 'End Game'

The fan excitement escalated when a TikTok video captured a moment during the surprise song segment featuring Taylor's performance of her 'Reputation' track, 'End Game'. This love song expresses the desire to be someone's "endgame" and reflects on the prospect of a life with a new romantic partner.

What caught the attention of eagle-eyed fans was the shift in the light-up bracelets worn by concertgoers. As Taylor began playing 'End Game', the bracelets transitioned from blue light to red and gold—the unmistakable colors of the Kansas City Chiefs, the NFL team for which Kelce plays. Many fans interpreted this color choice as an intentional nod to the Chiefs tight end, who was reportedly in attendance.

This subtle reference follows a more direct acknowledgment during Taylor's performance of 'Karma', where she altered a lyric to say, "Karma is the guy on the Chiefs coming straight home to me." The audience erupted in cheers as Taylor playfully hinted at her relationship with Kelce.

After the show, the visual narrative continued as Taylor was seen running backstage into Kelce's arms. The affectionate embrace was sealed with a kiss, marking a beautiful night for the enamored couple.

Taking to Instagram after the South American leg of her tour, Taylor shared her excitement about the successful concerts. The caption was accompanied by emojis, the first of which was a kissing one. Fans speculated that the lipstick mark was yet another subtle shoutout to Kelce.

A third wrote, "Whoever heard the mashup live… I HOPE YOU KNOW HOW LUCKY YOU ARE." "Beautiful and flawless performances all weekend… brilliant, as usual," stated a user. "Still processing the loss of the very first night," another tweet read.
