It hasn't been a "Cruel Summer" for Kansas City Chiefs tight end Travis Kelce, who has taken the pop culture world by storm with his budding romance with pop superstar Taylor Swift. In fact, it's been a modern-day "Love Story."

The power couple first broke the internet when Swift accepted Kelce's invitation to watch him play at Arrowhead Stadium in September after he watched her rock the same stadium during her wildly popular "Eras Tour" this summer. The duo have continued to captivate headlines since, with Kelce even being asked if he's in love with Swift.

"I'm going to keep my personal relationship personal," a coy Kelce said.

Although Kelce has vowed to keep his relationship private, the buildup to the romance between Kelce and Swift – or "Traylor," as some Swifties have nicknamed them – has been a public affair. From Kelce publicly courting Swift to her attending plenty Chiefs' games, here's a look at the couple's whirlwind relationship timeline:

Nov. 11: Travis Kelce attends Taylor Swift's Argentina concert

Travis Kelce is in Argentina! No, he's not playing another international NFL game following the Chiefs' 21-14 win over the Miami Dolphins in Frankfurt, Germany. He's spending his bye week supporting Taylor Swift at night two of her "Eras Tour" in Argentina. Social media footage showed Kelce singing along to Swift's "Blank Space." The two were spotted earlier holding hands.

Nov. 3: Travis Kelce mum on if Taylor Swift will attend Germany game

Ahead of the Chiefs' game against the Miami Dolphins in Frankfurt, Germany, on Nov. 5, Kelce was asked by reporters if Swift would be at Deutsche Bank Park. He declined to answer because of the boost he's gotten when she's seen him play in person.

"When I mention or everybody knows that she's at the game, the Vegas, the over-under on my catches kind of goes up and down, the spread goes up and down," Kelce joked. "I don't want to mess with any of that stuff, so I'm just going to keep it to myself."

The music superstar even debuted a celebratory handshake with Brittany Mahomes, wife of Chiefs quarterback Patrick Mahomes, in the suite they shared.

So the writers added in a Kelce appearance at the end and Swift introduced her friend Ice Spice, who was that evening's musical guest.

Paparazzi captured several photos of pop culture's hottest couple arriving at an "SNL" afterparty hand in hand. "They caught me with some weird hand-holding poses there," Kelce later admitted. "That was crazy."

Oct. 12: Taylor Swift attends third Chiefs game

Third time's a charm? Fresh off attending the premiere of her "Eras Tour" movie in Los Angeles a day earlier, Taylor Swift flew back to Kansas City to take in the Chiefs' 19-8 victory over the Denver Broncos on Oct. 12, marking the third Chiefs game she's attended this season.

The singer wore a black dress, paired with a red varsity jacket. She was then seen sitting next to Travis Kelce's mother, Donna Kelce, in a suite at Arrowhead Stadium. Kelce ended with nine catches and 124 receiving yards in the win, including a 19-yard catch that made Taylor Swift get up, cheer and embrace Brittany Mahomes.

Oct. 4: Travis Kelce says league 'overdoing' Taylor Swift coverage

Many fans believe the NFL is going overboard with its coverage of Kelce and Swift amid their rumored romance. Even Kelce says so.

"Is the NFL overdoing it? What is your honest opinion?" Jason Kelce asked Travis Kelce on their weekly "New Heights" podcast following the Chiefs' and New York Jets' "Sunday Night Football" matchup, where Swift was in attendance. Travis replied, "I think everybody is just overwhelmed... They're overdoing it a little bit."

The NFL is shaking off the criticism, saying that although it's playing into pop culture, the league's coverage is still "focused on the game, our players and variety of other initiatives."

"The Taylor Swift and Travis Kelce news has been a pop cultural moment we’ve leaned into in real time, as it’s an intersection of sport and entertainment, and we’ve seen an incredible amount of positivity around the sport," the league said in a statement obtained by ESPN.

Oct. 1: Taylor Swift attends Chiefs' 'SNF' game against the Jets

“Welcome to New York.” 

Swift was back to cheer on Travis Kelce during the Chiefs' Week 4 "Sunday Night Football" matchup against the New York Jets in MetLife Stadium in New Jersey, marking her second straight week attending a Chiefs game. She brought some friends along with her, including actors Blake Lively, Ryan Reynolds, Hugh Jackman and many Swifties that scrambled to buy tickets. (Swift had three shows at MetLife Stadium this summer as part of her "Eras Tour.")

The NBC broadcast cameras zoomed in on Swift chatting in a suite with Kelce's mom, Donna Kelce. The two looked close, smiling and whispering while Swift put her arm around Donna multiple times.

According to The Athletic, Swift was shown during the "Sunday Night Football" broadcast 17 different times. It paid off for NBC as Kansas City's 23-20 victory over the Jets was seen by an average of 27 million viewers. Following the Chiefs' win, the NFL temporarily changed its bio to "Chiefs are 2-0 as Swifties."

Sept. 27: Travis Kelce said Taylor Swift looked 'amazing' at game

In the podcast episode heard around the world, Kelce finally broke his silence on Swift's attendance at the Chiefs' Week 3 win over the Chicago Bears during a Sept. 27 episode of "New Heights."

"Shout out to Taylor for pulling up. That was pretty ballsy," Kelce started. "I just thought it was awesome how everybody in the suite had nothing but great things to say about her. The friends and family. She looked amazing, everybody was talking about her in a great light. And on top of that, the day went perfect for Chiefs fans, of course. We script it all ladies and gentlemen. It was just impressive."

TRAVIS KELCE shouts out Taylor Swift on his podcast for 'seeing me rock the stage'

Kelce continued: "To see the slow-motion chest-bumps, to see the high-fives with Mom, to see how Chiefs Kingdom was all excited she was there, that (stuff) was absolutely hysterical. It was definitely a game I’ll remember, that’s for damn sure."

September 2023: Swift-mania is born!

Swift and Kelce were spotted leaving the Chiefs' blowout win over the Chicago Bears together in a convertible, not only fueling dating rumors, but setting the entire internet on fire. Swift-mania was born.

"We just slid off in the getaway car in the end. Took my Chevelle to the game," Kelce said later. "Shout out to Taylor for coming through and seeing me rock the stage."

Kelce's jersey sales spiked 400%. He gained more than 250,000 Instagram followers. The Chiefs-Bears telecast brought in 24.3 million total viewers, the most-watched NFL broadcast of the week on any network. Heinz even announced a new "Ketchup and Seemingly Ranch" product after Swift was spotted eating chicken nuggets with both condiments at the game.

Sept. 24: Taylor Swift attends Chiefs game

Swift accepted Kelce's invitation to Arrowhead Stadium and attended the Kansas City Chiefs' 41-10 win over the Chicago Bears on Sept. 24. She was prominently featured during FOX's broadcast while sitting in a box next to Donna Kelce and cheering in a red hoodie.

Kelce was "Ready For It." He had a 3-yard touchdown catch from Patrick Mahomes, which caused Swift to erupt in cheers from the suite. After the matchup, Mahomes was asked by FOX's Erin Andrews if he had added expectations knowing the pop culture icon — and her fans — were watching.

"I heard she was in the house. I felt a little bit of pressure, so I knew I had to get it to Trav," he said. "And of course, it’s a route that Travis, he does his own thing and just makes up a route and I throw it to him. I think he wanted to get in the end zone just as much as all the Swifties wanted him to."

Sept. 21: Travis Kelce invites Taylor Swift to Chiefs game

During an appearance on "The Pat McAfee Show" on Sept. 21, Kelce was asked about his love life. He revealed that he "put the ball in her court" and invited the pop star to see a Chiefs game.

"I told her that I've seen her rock a stage in Arrowhead and she might have to come see me rock the stage at Arrowhead," Kelce said. "We'll see what happens in the near future."

Kelce added that it's "hilarious" how invested everyone is in his love life – "It's like that game 'telephone' where everybody is just whispering in each other's ears" – and Kelce ragged on his brother's role in the the whole thing.

"Guy is absolutely ridiculous," Travis said of his brother Jason Kelce, who added fuel to dating rumors by saying they're "100% true." "He can't stay out of the freakin' headlines. Please everybody stop asking my brother about my love life!"

Sept. 14: Jason Kelce says romance rumors are '100% true'

With rumors circulating about a link between his brother and Swift, Jason Kelce was put on the spot after his Philadelphia Eagles' win over the Minnesota Vikings on Sept. 14.

"I have a 15 year-old-daughter and she's a big fan of a certain pop star," Pro Football Hall of Famer Tony Gonzalez said to Jason Kelce on set of Amazon's "Thursday Night Football" postgame show. "You have a brother and I've been hearing rumors that there's maybe some stuff. Can you comment?"

Taking it in stride as others on set laughed (including Eagles quarterback Jalen Hurts), Jason Kelce carefully deflected the inquiry about his brother: "Everybody has been infatuated with Travis' love life, so I don't really know what's going on there. I know Trav is having fun and we'll see what happens with whoever he ends up with!"

DATING? Jason Kelce jokes Travis Kelce-Taylor Swift love story is '100% true'

During a radio appearance a few days later, Jason Kelce was (obviously) asked again about the rumors. It's a love story and his brother said yes ... sort of.

"I try to keep his business kind of his business, stay out of that world. But having said that, I think he's doing great and I think it's all 100% true," Jason Kelce told the 94WIP Morning Show on Sept. 20. After making the comments, he said "Nah, I'm joking, I don't know what's happening."

July 26: Travis Kelce says he shot his shot at Taylor Swift. It failed.

During a July episode of the "New Heights" podcast, which Kelce shares with brother Jason Kelce, the younger brother admitted that Taylor Swift unknowingly punted his advance to meet her after her concert. Kelce explained that he made a friendship bracelet especially for Swift, a concert tradition among Swifties in honor of lyrics from her 2022 song “You’re On Your Own, Kid.”

“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. So I was a little butt-hurt I didn’t get to hand her one of the bracelets I made for her," Kelce told his brother. "I wanted to give Taylor Swift one with my number on it."

He added: "She didn't want to meet me, so I take it personal."
