Taylor Swift sparks 'Rep TV' buzz with new 'Ready For It?' promo

Taylor Swift has fuelled the flames of Reputation (Taylor's Version) theories with a subtle move during her husband Travis Kelce's NFL game.

The 36-year-old pop superstar authorised the use of her song, ...Ready For It? from her 2017 album for a promotional video featuring Nikki Glaser which played before the Kanas City Chiefs' game began.

The Opalite hitmaker was in attendance herself at the Arrowhead Stadium, and the commercial paid several nods to her, including a jersey which supposedly belonged to Kelce, and read "Taylor's husband."

Noticing the song, Swifties flocked to social media and speculated about what it means for the Easter Eggs the Grammy winner has been dropping.

One fan wrote, "Nikki Glaser talking about the Chiefs while Taylor Swift is playing in the background. WOW," while another chimed in, "Am I the only one that's low key freaking out about it? Like it could be absolutely nothing but it could be something after the Emmy's Law and Order SVU skit..."

A third noted, "Its honestly the best football song!," and another exclaimed, "READY FOR IT SET ME OFF LIKE A FUCKING SLEEPER AGENT BRO."

Another agreed, "SAME! My jaw was on the floor and now I'm clowning for SOMETHING soon."
