Jason’s wife looked unfazed by his decision to strip down in the Buffalo winter on Sunday

Kylie Kelce didn’t seem too surprised by her husband Jason’s shirtless antics on Sunday night!

After the NFL center, 36, let out a scream and pulled his shirt off in the stands of Highmark Stadium — during a game in which his brother Travis scored two touchdowns for the Kansas City Chiefs during their divisional round win against the Buffalo Bills — Kylie’s reaction, or non-reaction, has gone viral.

In a post shared to X (formerly Twitter) of Sunday’s NFL broadcast, Kylie, 31, can be seen standing a few people behind her husband during the game in Orchard Park, New York as she chewed gum, gently smiled and clapped her hands.

“My favorite part is Kylie Kelce looking absolutely unfazed in the back,” one social media user wrote, in a post that has since earned over 50,000 likes as of Monday afternoon.

“kylie in the back like ‘yea that’s my husband,’ ” another Kelce family fan added.

Another X user shared a video of Jason after he jumped out of the suite, as someone inside tells the Eagles center, “Hey, Kylie said get your a– back in here.”

Kylie’s reaction to Jason’s public display of excitement comes as the Chiefs left Buffalo victorious following a 27-24 victory agains the Bills. The team will continue on to Sunday’s 2024 AFC Championship Game, where they face the Baltimore Ravens.

But Kylie wasn’t the only Kelce whose reaction to Jason’s shirtless antics made waves online. The Philadelphia Eagles player’s middle daughter, 2½-year-old Elliotte, also had some things to say.

Shortly after the game, Kelce shared a text from “Ma” — presumably Kylie’s mom — to X. The message read, “Ellie said ‘Dads boobs are showing!’ ”

“Buffalo is awesome, the energy is contagious,” Jason captioned the photo. “Such an incredible experience!!”

Jason and Kylie also share daughters Wyatt Elizabeth, 4, and Bennett Llewellyn, 11 months.

Throughout Sunday night, Jason could be seen sitting alongside his wife, mom Donna Kelce, father Ed Kelce, Taylor Swift and Chiefs quarterback Patrick Mahomes’ wife, Brittany Mahomes.

Earlier this week, Jason told reporters that he was thinking about going to see his little brother, 34, play in the playoffs after his Eagles were eliminated, adding that he doesn’t “get to watch him play very often.”

While Jason may not be continuing toward a hopeful Super Bowl ring this year like Travis, Eagles quarterback Jalen Hurts spoke to reporters about the center’s overall impact on the franchise, calling him “a legend in the city — really in the league,” who will “forever have a special place in my heart,” ESPN reported. Jason’s retirement from the NFL remains uncertain following the 2023-24 season.

“I don’t want to do a disservice to him and the things he’s been able to do and overcome. His journey to where he is now didn’t come easy. It’s been a long, long time coming for him, and every year since I’ve been here it’s been, ‘Are you going to come back?’ ” Hurts said.
