A timeline of Taylor Swift and Travis Kelce's budding romance

Rumors of a romantic connection between "Shake It Off" singer Taylor Swift and Kansas City Chiefs tight end Travis Kelce ignited in September, a month when Swift attended several of Kelce's games.

Kelce himself disclosed that he extended an invitation to Swift to join him at one of his games during an appearance on "The Pat McAfee Show" podcast. Their romance appeared to take a step forward in October when they were photographed hand in hand at a "Saturday Night Live" after-party. 

Here’s a complete timeline of their rumored relationship.

Swifties notices Kelce's presence at Swift's "Eras Tour" at Arrowhead Stadium, the very venue where he plays for the Kansas City Chiefs. Observers spotted the football sensation enjoying the show from his exclusive box and even engaging with fans inside the venue by exchanging friendship bracelets.

CHIEFS STAR TRAVIS KELCE BUYS NEW KANSAS CITY HOME AMID RUMORED ROMANCE WITH TAYLOR SWIFT: REPORTS

A few weeks following his attendance at Swift's concert, Kelce openly shared that he had made an attempt – and failed – to meet Swift after the performance.

On ESPN's "SportsCenter," reporter Adam Schefter playfully hinted at the dating rumors surrounding Kelce and Swift while discussing the player with anchor Kevin Negandhi. Schefter cleverly incorporated Swift's song titles into his conversation, adding a lighthearted touch to the discussion.

Swift unexpectedly joined Travis Kelce at the Chiefs game on Sept. 24. Observers spotted the singer in Kelce's suite, accompanied by his mother, Donna Kelce. She was later caught enthusiastically cheering as Kelce scored a touchdown.

During one of the episodes of his weekly podcast, "New Heights with Jason and Travis Kelce Presented by Wave Sports + Entertainment," Kelce expressed his contentment with life, and he enthusiastically remarked on the weekend, especially as he reminisced about his time spent with Swift.

Swift was spotted at MetLife Stadium again when the Chiefs played the New York Jets in New Jersey. She was accompanied by several of her famous friends including Blake Lively, Ryan Reynolds, Hugh Jackman, Sabrina Carpenter, Sophie Turner and Antoni Porowski.

Following her appearance at the premiere of her "Eras Tour" film in Los Angeles, Swift promptly traveled back to Kansas City to catch Kelce's game at Arrowhead Stadium. During the game, she was observed socializing with Brittany Mahomes, Patrick Mahomes' wife, and Kelce's parents.

During the Oct. 14 episode of "Saturday Night Live," both Swift and Kelce made unexpected appearances on the show. Swift was there to introduce Ice Spice, the musical guest, while Kelce was featured in a humorous skit centered around the NFL's fascination with Swift coverage.

After the show, the two were spotted hand in hand in New York City as they headed to the "SNL" after-party at Catch Steak.
