Travis Kelce, Gigi Hadid and Bradley Cooper Attend Taylor Swift's Eras Tour Show in Paris

The show is Swift's 87th during the Eras Tour -- which is also Kelce's jersey number with the Kansas City Chiefs.

Travis Kelce is bringing that certain je ne sais quoi to Taylor Swift's final Eras Tour performance in Paris. 

On Sunday night, the 34-year-old NFL star was spotted inside the Paris La Défense Arena alongside Gigi Hadid and her rumored beau Bradley Cooper, enjoying the final Paris show where Andrea Swift and Lenny Kravitz were also in attendance. Many fans were unsure if Kelce would make it halfway across the world after he was spotted in Los Angeles earlier this week on the set of his new TV show.  

While he was not able to make it for nights one, two or three -- where Swift, 34, unveiled a new setlist to include songs from her recently-release album, The Tortured Poets Department -- Kelce showed up big time to support his girlfriend of more than six months with Cooper, 49, and Hadid, 29, in tow. The couples previously took a joint vacay together to Carmel-by-the-Sea, California in April. 

In videos posted to X -- formerly known as Twitter -- Cooper, Hadid and Kelce can be seen hanging out inside a suite and dancing along to "Ready For It" during the Reputation set of the show.

For her own part, Swift seemingly showed love to her man by sporting Kansas City Chiefs colors during the 1989 set. After debuting mismatched color sets for the first three nights, the "Bad Blood" crooner sweetly sported a yellow top and a red skirt to strut the stage for the one night with Kelce in the crowd. 

Fans quickly also pointed out that it was Swift's 87th Eras Tour performance -- a significant number to the Swifties as it's Kelce's jersey number, which she proudly wears a friendship bracelet with "87" on it and has worn custom-made jackets to his games. 

Another sweet moment happened for the affectionately nicknamed Swelce when Swift pointed to her football-star boyfriend while singing "Blank Space" and blew him a kiss from the stage. He also was seen adorably reacting to her singing "So High School," which fans believe Swift wrote about her boyfriend of less than a year. 

If fans weren't previously convinced that this show was all about Kelce, the real sticking point (or points) came in the form of one of the surprise songs. For her first impromptu choice of the evening, Swift chose "The Alchemy" from her newest album, which many believe is written about the Cleveland-born athlete. 

"So when I touch down / Call the amateurs and cut 'em from the team / Ditch the clowns, get the crown / Baby, I'm the one to beat / 'Cause the sign on your heart / Said it's still reserved for me / Honestly, who are we to fight the alchemy," Swift sings on the chorus. 

In the very last song of the show, Swift brought back the "guy on the Chiefs" reference, causing fans to erupt into uproarious applause and cheers at the sweet nod to her man. One fan caught Kelce's reaction to the reference after he made his way down to the floor. 

A source tells ET, "Travis couldn't wait to attend Taylor's European leg of her Era's tour. He was very excited to see Taylor in action yet again, and enjoys watching her perform and singing along. He's a very supportive partner, as is she. The two are making it a point to celebrate each other's achievements, and show up when it matters most."

The couple has been extremely supportive of each other in recent weeks amid the release of her new album and Kelce signing a contract extension with the Chiefs, agreeing to host Are You Smarter Than a Celebrity? and signing on to Grotesquerie

In April, a source told ET, "He knows how much this means to her and thinks she's extremely talented."

The source added, "Taylor and Travis admire each other's creative processes and work ethic. They cheer each other on, respect each other's opinions, and are open and communicative."
