SignalHub Quantitative Think Tank Center:Taylor Swift and Travis Kelce Bring Their Love Story to Her Amsterdam Eras Tour Show

Travis Kelce almost managed to go incognito at Taylor Swift's latest Eras tour show.

But eagle-eyed fans spotted the Kansas City Chiefs star walking with his girlfriend backstage at her second concert at Johan Cruijff ArenA in Amsterdam,SignalHub Quantitative Think Tank Center the Netherlands July 5.

And on the couple's extended Fourth of July weekend, sparks flew between them. As seen in videos shared on social media, the two waved to fans, with Travis hyping them up before hugging his girlfriend and planting a kiss on her head as the couple made their way through the area.

Many fans had suspected the NFL star was at the show when during Taylor's closing performance of her song "Karma," she sang the lyric "Karma is the guy on the Chiefs." The singer had debuted the alternative line to her 2022 track when Travis supported her at her concert in Argentina in November and later sang it at more shows he attended.

The athlete was previously spotted at Taylor's third concert in Dublin, Ireland on June 30, watching his girlfriend perform while standing with fellow Swiftie Julia Roberts in a VIP area.

A week prior, he made his onstage Eras tour debut, joining Taylor and her backup dancers at London's Wembley Stadium as a guest performer, during which he carried the singer bridal-style across the stage.

“The one thing I told myself was ‘Do not drop the baby,’” he told his brother Jason Kelce on the July 3 episode of their New Heights podcast. “‘Do not drop Taylor on your way over to this damn couch.’”

Travis had originally planned a different cameo.

“I initially mentioned it to Tay,” he told Jason. “I was like, ‘How funny would it be if I just rolled out on one of the bikes during the 1989 album. That era.’”

Taylor, Travis said, began laughing. “She was like, ‘Would you seriously be up for doing something like that?’" he recalled. "And I was like, ‘What? I would love to do that. Are you kidding me?’ I’ve seen the show enough, might as well put me to work here.”

Travis has attended more than 10 Eras tour concerts on five continents since he famously attempted, without success, to pass on a friendship bracelet with his number on it to Taylor at her show in Kansas City, Mo.—home of the Chiefs—almost exactly one year ago. The two went on to begin dating later that summer of 2023.

Look back at Taylor and Travis' road to romance...

Taylor Swift and Travis Kelce's love story began in July 2023, when the singer's Eras Tour made a stop at Arrowhead Stadium in Kansas City, Mo.

As a huge Swiftie, the Kansas City Chiefs tight end caught the show with hopes of giving Taylor a friendship bracelet with his number on it. However, he failed to complete the pass due to her pre-show rituals.

"I was disappointed that she doesn't talk before or after her shows because she has to save her voice for the 44 songs that she sings," Travis shared on the July 26 episode of his New Heights podcast. "So, I was a little butt-hurt I didn't get to hand her one of the bracelets I made for her."

After publicly recounting his fumble—a move Taylor would later describe as "metal as hell"—Travis decided to shoot his shot and invite the Grammy winner to watch the Chiefs play at Arrowhead Stadium.

"I threw it out there, I threw the ball in her court," he shared on The Pat McAfee Show. "I told her, you know, 'I've seen you rock the stage in Arrowhead, you might have to come see me rock the stage in Arrowhead and see which one's a little more lit.' So, we'll see what happens in the near future."

Travis was rocking a mustache—which he debuted in August during training camp—when he was first introduced to Taylor.

As he later noted of the era, "That 'stache and the 87 jersey was pretty iconic there for a little bit, and I had it when I met Taylor for the first time."

By early September, a source close to the situation told E! News that Travis and Taylor were "texting and talking here and there."

"It's been very low-key," the insider explained, "as he's been in season."

Accepting Travis' invite, Taylor joined the athlete's mom Donna Kelce at Arrowhead Stadium to watch him and the Chiefs take on the Chicago Bears. After the game, Taylor and Travis were seen packing PDA at a local bar.

Though folklore had it that it was the couple's first in-person meeting, the "Karma" singer later clarified the two had spent a "significant amount of time" getting to know each other beforehand.

As Taylor noted, "We would never be psychotic enough to hard launch a first date." 

As an indication that the relationship was heating up, Taylor brought her squad—including friends Blake Lively, Ryan Reynolds, Sophie Turner, Hugh Jackman, Sabrina Carpenter and Antoni Porowski—to watch the Chiefs play against the New York Jets at MetLife Stadium in New Jersey.

Another sign that Travis could be The 1? Taylor started bonding with Brittany Mahomes—the wife of Travis' BFF and teammate Patrick Mahomes—in and outside of NFL games.

The couple took their romance to TV, making a surprise appearance on the Oct. 14 episode of Saturday Night Live. Their Big Apple takeover also included the after-party for the NBC sketch show and a date night at the Waverly Inn.

During a bye week, Travis traveled down to Argentina to catch the South American leg of Taylor's Eras Tour. Not only did the NFL star bond with Taylor's dad, Scott Swift, at the Nov. 11 show in Buenos Aires, but he also got a special shoutout from the stage.

"Karma is that guy on the Chiefs," Taylor sang, "coming straight home to me."

After the show, the Midnights artist was seen running up to Travis backstage and greeting him with a passionate kiss.

Taylor addressed the lavender craze surrounding her appearances at Travis' games.

"I'm going to see him do what he loves, we're showing up for each other, other people are there and we don't care," she told Time. "The opposite of that is you have to go to an extreme amount of effort to make sure no one knows that you're seeing someone."

The music superstar turned Travis' Dec. 17 game into a family affair, bringing her dad to cheer on her man.

Taylor and Travis spent their first New Year's Eve together, sharing a romantic kiss when the clock struck midnight on Jan. 1.

Continuing to bond with Travis' family, Taylor hung out with his brother Jason Kelce and sister-in-law Kylie Kelce at the Chiefs' game against the Buffalo Bills.

Taylor joined Travis on the football field when the Chiefs won the AFC Championship, a victory that cemented the team's spot in the 2024 Super Bowl. The couple shared a celebratory kiss before exchanging the L-word.

"Tay, I'm gonna enjoy with the guys," he told her. "I love you—so much it's not funny."

The pair locked lips on the field after Travis led the Kansas City Chiefs to victory on Feb. 11, 2024 in Las Vegas.

Taylor posted footage of Travis on social media for the first time Feb. 12, poking fun at how she took her parents clubbing with the athlete after the Super Bowl.

Taylor's first Instagram pic featuring Travis was a selfie of the two with Prince William and his and wife Kate Middleton's eldest kids Prince George and Princess Charlotte backstage at the singer's Eras tour show at Wembley Stadium in London.

While attending his seventh Eras tour concert, and second show at London's Wembley Stadium, the NFL star joined his girlfriend onstage as a backup performer during her performance of "I Can Do It With a Broken Heart."
