‘Tis the damn football season.

Taylor Swift and her brother, Austin, celebrated a must-see Chiefs touchdown during the game against the Cincinnati Bengals on Sunday.

The “Fortnight” singer wrapped her arms around her sibling and the pair jumped up and down with joy after wide receiver Rashee Rice corralled a deep ball from Patrick Mahomes and ran it into the end zone, evening up the score at 10.

She and brother Austin jumped up and down after Patrick Mahomes threw a deep ball to wide receiver Rashee Rice for the score.

Swift high-fived those around her in the suite.

At one point, she appeared in joyful disbelief that the Chiefs tied the game.

Swift, 34, cheered and high-fived others in the Kelce suite — including the tight end’s parents, her own mother and longtime pal Danielle Haim.

At one point, she appeared overwhelmed by the excitement and put her face in her hands as she shook her head in disbelief at the epic play.

The pop star looked spirited in a vintage Chiefs jersey, which she wore as a dress, and black leather over-the-knee boots.

Sunday night’s game marked the 15th Chiefs game Swift has attended since she started dating the 34-year-old pro athlete last summer.

Despite backlash from NFL fans regarding her screen time, Swift previously told Time that she is “just there to support Travis” and has “no idea” how often she is shown on TV.

“When you say a relationship is public, that means I’m going to see him do what he loves, we’re showing up for each other, other people are there and we don’t care,” she told the magazine.

“The opposite of that is you have to go to an extreme amount of effort to make sure no one knows that you’re seeing someone,” she continued. “And we’re just proud of each other.”

Swift has fully embraced her new role as a WAG and is often captured celebrating Kelce’s big moments in the stands.

Nearly two weeks ago, the “Lover” singer was spotted “blushing” and hugging Donna after Kelce completed his first pass of the 2024-2025 season.

Later on in the game, Swift was seen doing a snippet of her Eras Tour choreography for her song, “So High School,” which is about her relationship with Kelce.

The 14-time Grammy winner busted out the move after the three-time Super Bowl champion caught a pass from quarterback Patrick Mahomes.

Following the “fantastic” win, the couple posed for a few loved-up photos before leaving Arrowhead Stadium hand in hand.

They later joined the rest of Kelce’s teammates for an afterparty at a rooftop bar downtown, where we’re told Swift let loose a little.
