Taylor Swift’s mom Andrea Swift is showing her support for both her daughter and boyfriend Travis Kelce as he takes on the Cincinnati Bengals.

On Sunday, Sept. 15, just before the Chiefs took on the Cincinnati Bengals at Kansas City’s Arrowhead Stadium, the “Fortnight” singer, 34, and her mom, 66, were spotted arriving at the game to cheer on the tight end. After photographers and fans snapped photos of the mother-daughter duo arriving on a golf cart to the field, one detail on Andrea’s outfit stood out as a custom nod to Kelce and her daughter.

Some eagle-eyed fans noticed that Andrea was wearing a pin on her button-down Chiefs-branded shirt that read: “in my 87 era,” referring to Kelce’s jersey number and referencing Swift’s multi-billion dollar Eras Tour.

Earlier on Sunday, Swift could be seen arriving to Arrowhead Stadium in a video captured by CBSwith Haim band members (and sisters) Danielle and Este Haim walking alongside her, also sporting red outfits to support the Kansas City team. Este’s boyfriend, tech entrepreneur Jonathan Levin, also joined Swift’s crew.

Swift showed her own support for the Chiefs and Kelce with her look, an oversized vintage 90s Chiefs t-shirt as a dress, and her drink.

One fan captured video of the Tortured Poets Department musician sipping from a custom cup labeled with Kelce’s number, and another video showed the singer and her brother Austin Swift celebrating and jumping up and down together after the Chiefs successfully secured a touchdown. Yet another video showed the singer seemingly shaking her head and saying “unbelievable” after the Bengals scored a touchdown.

The 14-time Grammy winner has become a fixture at the Chiefs games since the start of her relationship with Kelce, 34, began nearly one year ago.

Swift previously attended the NFL 2024 season-opening game on Sept. 5, hanging out with her boyfriend’s parents Ed and Donna Kelce as the Chiefs beat the Baltimore Ravens. She joined Kelce and his teammates to celebrate their win at the Kansas City bar Prime Social that night following the game, with a source telling PEOPLE that “everyone partied hard.”

“A good time was definitely had,” the insider said, adding, “Travis and Taylor both let loose.”

The couple were also spotted out and about in New York City for following last weekend’s game. They grabbed dinner at Lucali in Brooklyn, attended the wedding of model Karen Elson and Electric Lady Studios owner Lee Foster.

Swift and Kelce also spent time with their friends and the tight end’s teammate Patrick and Brittany Mahomes at the the men’s final of the US Open.
