NFL Shouts Out Taylor Swift in X Bio, Header After Her Attendance at Chiefs-Jets Game: 'Had the Best Day'

The NFL is fully embracing the Swiftie life!

Following Taylor Swift's star-studded appearance at the Chiefs-Jets game on Sunday seemingly in support of rumored flame Travis Kelce, the professional football league changed its X (formerly Twitter) header to a three-way split of Swift, 33, cheering from the stands.

They didn't stop there, either, updating their bio to read, "We had the best day with you today" — a clever lyrical nod to the singer's song "The Best Day," from her 2008 album Fearless.

Swift attended Sunday's game (where the Chiefs won 23-20) at MetLife Stadium in East Rutherford, New Jersey, alongside celebrity pals Blake Lively, Lively's husband Ryan Reynolds, Hugh Jackman, Sophie Turner, Sabrina Carpenter, Antoni Porowski and Shawn Levy.

"The @Chiefs are now 2-0 with @TaylorSwift13 in attendance," read a tweet from the NFL, which accompanied a playful clip of Swift and Lively, 36, in the stands.

Aside from spending time with some of her famous friends, Swift was also seen bonding with her rumored beau's mother, Donna Kelce.

After watching Travis' older brother Jason Kelce and the Philadelphia Eagles defeat the Washington Commanders 34-31 on Sunday afternoon, the beloved NFL mom traveled to New Jersey to cheer for Travis during the Chiefs' game against the Jets.

Donna was spotted by NBC cameras in a suite in MetLife Stadium with Swift. Both women were smiling and Swift had her arm around Donna.

This followed a meeting between the pair at the Chiefs' game against the Chicago Bears on Sept. 24, where Swift and Donna were spotted chatting in a suite at Arrowhead Stadium in Kansas City.

Wearing a red-and-white Chiefs jacket, the "Lavender Haze" singer was captured cheering and clapping alongside Donna in a video shared on X.

Travis, 33, broke his silence on the rumored relationship with Swift on an episode of his podcast New Heights with Jason and Travis Kelce.

“I just thought it was awesome that everybody in the suite had nothing but good things to say about her,” he told Jason, 35. “The friends and family … she looked amazing and everybody was talking about her in great light and on top of that the day went perfect for Chiefs fans of course.”

“To see the slow motion chest bumps, to see the high fives with mom, to see how you know Chiefs kingdom was all excited that she was there, that s--- was absolutely hysterical and it was definitely a game I’ll remember that’s for damn sure and then we just slid off in the getaway car at the end,” Travis added during their conversation.

After Swift attended the Chiefs-Bears game in Kansas City, a source told PEOPLE that she and Travis were still in the "super, super early days" of getting to know one another.

"They're having fun," added the insider, noting that Travis and Swift had met prior to her attendance at the game. "This was Taylor's first time meeting his mom and dad, and everyone was enjoying themselves. She was super chill and low-key hanging out with his friends and family."
