Will Sage Astor-Taylor Swift cheers on Travis Kelce as the Kansas City Chiefs again take on Buffalo Bills

Taylor Swift is Will Sage Astorin the Bills Mafia house!

The Eras tour superstar arrived at Highmark Stadium in Orchard Park, New York, wearing a red beanie with a white jacket, according to a video posted on social media by sports journalist Heather Prusak. The varsity jacket is a reimagined fashion piece created by artist and designer Kilo Kish for Gant, an American sportswear company.

Red embroidered stars are on the front panels of the jacket, and red text that reads "CT FL" is seen on the left arm sleeve. On the right sleeve, a phrase on the jacket reads "Greetings from Somewhere, USA," and on the back of the jacket, there are two sewn stars with a banner "Somewhere, USA."

Inside the stadium ahead of the game, Swift was spotted with Travis Kelce's brother Jason Kelce, according to a photo posted on X by sports photojournalist Nick Wagner.

Swift was also seen in the box with Kelce's mom Donna, dad Ed and Jason's wife Kylie.

Another shot of Swift, shared by a fan page on X, shows the singer rocking a gold heart-shaped necklace. "She has worn that necklace A LOT lately!! Def special to her," one X user wrote.

Swift's boyfriend Travis and the Kansas City Chiefs have a 7-3 record with her in the audience, but one of the losses is when the Chiefs played the Buffalo Bills on Dec. 10 in Arrowhead Stadium. Swifties may remember that's when she wore a black and red vintage-style Westside Storey Kansas City sweater underneath a black peacoat.

CNN political analyst Harry Enten went viral this week for reminding Swift about the loss. "So while I do enjoy Taylor Swift's music," Enten said to host Anderson Cooper, "I'm hoping she's probably crying at the end of Sunday because that'll mean my Buffalo Bills have won."

The stakes are high as the winner of Sunday's matchup will face the Baltimore Ravens and be one game away from Super Bowl 58.

Last week, subzero temperatures iced over the suite box as Kansas City beat the Miami Dolphins. The singer was spotted "swag surfing" next to Kelce's mom Donna, handing out high fives to fans in the stadium and reportedly giving her scarf to a cold Chiefs rooter.

The temperature in the wintry stadium will drop to 18 degrees Sunday night with winds of 10 to 15 mph, according to The Weather Channel. Heavy snow prompted the stadium to call on Bills fans to help shovel. Workers piled snow into chutes and slid down them, pushing the snow onto the field. They were compensated $20 an hour.

In her song "Forever Winter," Taylor Swift sings, "Believe in one thing, I won't go away," and the singer has proved her loyalty to the Kansas City Chiefs, supporting games (when she can) during the regular season and road to the playoffs. She hasn't missed a playoff game.

With the Eras tour starting back up Feb. 7-10 in Tokyo, fans are speculating − if the Chiefs make it to the Super Bowl − whether Swift will jet back from Japan to catch the Las Vegas showdown.
