Taylor Swift’s mother Andrea Swift is showing her support for her daughter and boyfriend Travis Kelce, who is taking on the Cincinnati Bengals.

On Sunday, September 15, just before the Chiefs took on the Cincinnati Bengals at Arrowhead Stadium in Kansas City, the 34-year-old “Fortnight” singer and her 66-year-old mother 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 about Andrea’s outfit stood out as a nod to Kelce and her daughter.

Some keen-eyed fans noticed that Andrea was wearing a pin on her Chiefs jersey that read “in my 87 era,” a reference to Kelce’s jersey number and Swift’s multi-billion dollar Eras Tour.

Earlier on Sunday, Swift was seen arriving at Arrowhead Stadium in a video released by CBS, with Haim bandmates (and sisters) Danielle and Este Haim walking alongside her, also wearing red outfits to support the Kansas City team. Este’s boyfriend, tech entrepreneur Jonathan Levin, also joined Swift’s crew.

Swift showed her support for the Chiefs and Kelce with her look, an oversized vintage ’90s Chiefs T-shirt as a dress and her drink.

A fan made a video of the Department of Tormented Poets musician sipping from a custom mug with Kelce’s number on it, while another video showed the singer and her brother Austin Swift celebrating together and jumping up and down after the Chiefs successfully scored a touchdown. Yet another video showed the singer apparently shaking her head and saying “unbelievable” after the Bengals scored a touchdown.

The 14-time Grammy winner has been a regular at Chiefs games since her relationship with Kelce, 34, began nearly a year ago.

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

“We definitely had a good time,” the insider said, adding, “Travis and Taylor both let their hair down.”

The couple was also spotted in New York City watching the game this past weekend, grabbing dinner at Lucali in Brooklyn, and attending the wedding of model Karen Elson and Electric Lady Studios owner Lee Foster.

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