Taylor Swift was pictured for the first time with Travis Kelce’s brother Jason on Sunday night, cheering on the Kansas City Chiefs against the Buffalo Bills.

With the Philadelphia Eagles out of the playoffs, Jason and Kylie traveled to Buffalo to cheer on Travis in his own game. He was caught on camera wearing a red t-shirt with the words ‘Big Yeti’ and drinking a beer just before the game started.

It is the first time they have been photographed with the pop star since they announced their relationship in late September, when she went to Arrowhead Stadium in Kansas City to cheer on the Chiefs against the Bears.

There have recently been reports that Swift has a ‘awkward relationship’ with Jason and Kylie, who are more introverted than Travis, and this was before he began dating the world’s most famous person.

Kylie even stated in November that she prefers to watch games from the stands with fans rather than in a suite – but given the 20-degree weather in Buffalo on Sunday night, it was a good time to make an exception.

They came out in force to cheer Travis and the Chiefs on against the Bills on Sunday night.

Before meeting Swift, Jason was filmed tailgating with Bills fans and drinking beer with them in the cold weather.

Jason and Taylor were expected to meet in November when the Chiefs hosted the Eagles on Monday Night Football at Arrowhead, with Swift returning from her Eras Tour performance in Brazil.

However, Swift had to postpone a concert to the night of the game, so she was unable to return to the United States on time.

Ironically, before dating Travis, Swift openly expressed her fandom for the Philadelphia Eagles, the team Jason plays for.

Swift told fans at a Philadelphia show in May last year that she supports the Eagles before performing the song ‘Gold Rush’, which contains a reference to a ‘Eagles t-shirt’ in the lyrics.

She told the thousands of fans at her show: ‘I don’t know how big the debate was, but I saw it.

“I have a lyric that says, ‘With my Eagles t-shirt hanging from the door.’ I noticed some people wondering if it was the band the Eagles or the team the Eagles, and while I love the band the Eagles, come on, guys. I’m from Philadelphia. Of course, it is the team.

But ever since she met Travis, she has been wearing Chiefs gear.

Some hardcore Swift fans held up signs to welcome her to Buffalo.

Swift sat with Travis and Jason’s mother, Donna, at her first Chiefs game, and she has since met their father, Ed, at other games.

However, given Jason’s own schedule throughout the season, as well as Taylor touring during the regular season, this is the first time she has met her potential future brother-in-law.

Travis and Jason are very close off the field. Travis wears No. 87 for the Chiefs because that is the year his older brother was born, and they were Super Bowl rivals last year when the Chiefs played the Eagles.

Jason, meanwhile, is considering his own NFL future.

He reportedly informed his Eagles teammates in the locker room on Monday night that he was retiring, but an official announcement has yet to be made.
