Taylor Swift was visibly shocked by Jason Kelce’s shirtless celebration as her boyfriend, Travis Kelce, and the Kansas City Chiefs faced off against the Buffalo Bills Sunday.

The pop star covered her face with her hands as the Philadelphia Eagles center ripped off his tee in the freezing weather and jumped down from their VIP suite at Highmark Stadium into the stands.

“yes queen that’s your future brother in law,” one fan jokingly tweeted.

The enthusiastic reaction came after his younger brother scored a touchdown in the second quarter — his first in eight games.

A shirtless Jason, 36, was also dubbed “No. 1 hype man” by the Kansas City Chiefs’ social media account after he was captured roaring into the night with a beer in hand following the big play.

The divisional round playoff game marked the first time the “Bad Blood” singer, 34, has been seen hanging out with Jason and his wife, Kylie Kelce, since she began dating Travis in July 2023.

The trio was photographed chatting with each other in the suite after traveling to upstate New York to support Travis.

The NFL brothers’ parents, Donna and Ed Kelce, were also in attendance for the matchup.

In the midst of the intense action on the field, the Chiefs’ tight end, 34, still had his girlfriend on his mind after his second-quarter touchdown.

Travis gave a romantic nod to Swift by flashing her signature heart gesture to the crowd in celebration. He also blew a kiss seemingly in the direction of her box.
