"This all started when Travis very adorably put me on blast on his podcast, which I thought was metal as hell," she told Time. "We started hanging out right after that. So we actually had a significant amount of time that no one knew, which I'm grateful for, because we got to get to know each other."
"By the time I went to that first game, we were a couple," Swift continued. "I think some people think that they saw our first date at that game? We would never be psychotic enough to hard launch a first date."
For her second appearance, she brought her longtime pal Blake Lively.
Swift and Lively watched the Chiefs defeat the New York Jets at MetLife Stadium in East Rutherford, New Jersey — where Swift had performed three sold-out concerts just a few months prior.
The October game drew the highest viewership for a Sunday TV show since the Super Bowl, NBC Sports reported.
"I think it's fun when they show who all is at the game. I think it brings a little more to the atmosphere, brings a little bit more to what you're watching," Kelce said during an episode of his "New Heights" podcast.
"But at the same time, I think they're overdoing it a little bit," Kelce continued. "For sure, especially for my situation. I think they're just trying to have fun with it."
Swift has struck up a friendship with Brittany Mahomes, who's married to Kelce's teammate.

The store's owner, Chris Harrington, told Business Insider he originally thought Swift's order — which totaled $1,200 for curated vintage pieces — could be fraudulent.
Instead, she wore one of those pieces at Arrowhead Stadium in December, causing a surge of traffic to Westside Storey's website.
"We've had hundreds of orders over the last 48 hours," Harrington told BI. "Sometimes our online store lights up after a Chiefs game when we win, but this is 100 times more than that, and we lost the game. It was the Taylor effect."
She brought her dad and friends to cheer for the Chiefs in Foxborough, Massachusetts.

"He actually made me feel like a child because his gift to me was straight out of the bag," Kelce said on his podcast "New Heights". "Whipped it out and handed me a VHS of my favorite football movie of all time."
She also spent New Year's Eve cheering for Kelce in Kansas City.

For her first game of 2024, Swift braved freezing temperatures to high-five fans.
