Taylor Swift looks on as Jason Kelce celebrates shirtless.

Jason Kelce wasn’t on the field when the Chiefs beat the Bills on Sunday night, but he was in the building. And he’s the one who’s been dominating the headlines since, with his shirtless celebration overshadowing his brother’s sensational performance.

The Philadelphia Eagles center, who could be retiring this year, left everyone surprised given the way he went wild, including his brother’s girlfriend, Taylor Swift.

 

The pop sensation appeared to be in utter shock watching her new brother-in-law jump out of their box in a semi-naked craze after Travis Kelce scored his first touchdown. It could be because she would have never expected such a thing, but a new video from inside the box suggests it could have been because she had just high-fived him a few seconds ago and was in awe over how fast he got out outside.

Check it out below:

 

Kelce has been getting praise online following his appearance at Highmark Stadium, having joined the Bills Mafia in their tailgating ahead of the game, while he also carried a young Bills fan to say hi to Swift during the match.

We’re all waiting to see whether he turns up in Baltimore this weekend.
