King of her heart.

Travis Kelce ensured Taylor Swift stayed on his mind when he was seen with what looked like the Eras Tour book tucked into his gym bag on Tuesday.

The Kansas City Chiefs player, 35, headed into a workout wearing an all-gray outfit and a backwards baseball cap, holding a duffel at his side.

A social media user zoomed in on what was inside the bag and noticed a recognizable pink design, which looked similar to the book’s cover unveiled in November 2024.

“HELLO IS THAT THE ERAS TOUR BOOK???” the Swiftie asked via X.

While some assumed that the football player was delivering an autographed copy of the book to a fan, others joked that he “longs for [the] eras tour just as much as” they do.

“He probably has Tay’s pop tarts to give to someone who works at the gym too,” one joked, referencing the dessert Swift is known for making.

“Imagine having a book full of your girlfriend if you miss her,” another wrote.

A separate fan gushed over “the concept of Travis treating the eras tour book like a photo album and whipping it out whenever anyone comes over like a proud family member and forcing them to look at it.”

Kelce has been in a relationship with the pop star since the summer of 2023.

While the couple spent much of this year out of the spotlight after wrapping her years-long tour and his 12th football season, they resurfaced multiple times this month.

On June 4, the duo were spotted holding hands during a Palm Beach, Fla., date night, with an eyewitness telling Page Six they were “giggly” and “adorable” together.

The pair packed on the PDA and laughed “lots.”

Later that same week, they attended Kelce’s cousin Tanner Corum’s Tennessee wedding to Samantha Pecj.

Eagle-eyed Swifties analyzed those photos as well, noticing that Kelce had some of the singer’s lipstick on his mouth in certain snaps.

“Man he can’t help it haha he just can’t,” one tweeted.

The couple sparked speculation that they are secretly married themselves when Cole Kmet’s event planner posted a photo of the invitation they received, addressed to “Taylor and Travis Kelce.”

However, some fans pointed out that “this is very common for couples (married and unmarried) for weddings … for aesthetic.”
