Taylor Swift performs The Alchemy for boyfriend Travis Kelce as a surprise during Paris set … track contains allusions to football and her beau

Taylor Swift appeared to pay homage to her boyfriend Travis Kelce during her show in Paris Sunday at La Defense Arena, including the song Alchemy as a surprise guitar track in her setlist.

The 34-year-old songstress had multiple costume changes in her set at the show Sunday, which was attended by the Kansas City Chiefs tight end, 34, as well as supermodel Gigi Hadid, 29, and A-list actor Bradley Cooper, 49, who were pictured sitting together in a luxury box.

The Grammy-winning musical artist blended her track The Alchemy – which fans have speculated is about her romance with the NFL star – with her track Treacherous, according to social media posts from the show.

The Alchemy, which is from Swift’s latest album The Tortured Poets Department, includes football-centric references to touchdowns, team play and ‘trying to be the greatest in the league,’ leading a number of the fans to conclude the singer-songwriter created the track as an ode to her ongoing romance.

There was a numerical tie-in to playing a song dedicated to Kelce during Sunday’s show: The concert was the 87th on Swift’s The Eras Tour, aligning with Kelce’s football jersey number, 87.
