Travis Kelce revealed how his girlfriend Taylor Swift felt about his brother Jason Kelce's shirtless antics during the Chiefs vs. Bills game last Sunday.

In a new episode of the Kelce brothers' "New Heights" podcast, they talked about the recent football matches, their wins and Jason going shirtless over the weekend.

"You celebrated my touchdown by taking off your shirt, screaming, jumping out of the suite, chugging a beer with the fans, then jumping back into the suite... I watched it, and it was pure pandemonium," Travis said, talking about his brother's shirtless moments in the presence of his girlfriend, Swift.

Jason said he gave his wife Kylie a heads-up about what he was about to do. However, he got a warning from the latter, telling him to be on his best behavior because Swift was with them in the suite.

"I gave Kylie a heads-up. The moment we got into the suite, I said I'm taking my shirt off, and I'm jumping out of that suite, and she said, 'Jason, don't you dare,'" Jason recalled.

He continued, "She was already telling me to be on my best behavior because we were meeting Taylor. She's like, 'Be on your best behavior.'"

"This is part of the charm. This is part of the Jason Kelce charm. I want to make my best first impression. This is my best chance," he added.

Per the Kansas City Chiefs tight end, Jason's charm seemed to have worked on his pop star girlfriend.

"Oh man, well, Tay said she absolutely loved you," Travis told his older brother.

During the AFC Divisional Playoff between the Kansas City Chiefs and the Buffalo Bills game on Sunday, the Philadelphia Eagles center also charmed the hearts of Swifties -- Taylor's fans.

After seeing a young girl holding a signage for Taylor, he climbed down the suite, picked up the girl and took her to the suite's window so she could say "Hi" to the singer.

He also picked up another girl, who appeared to be a fan and gave her a chance to take a photo with him.

Though Jason was shirtless at the time, everyone was comfortable, including the girls' parents, per TMZ. Everyone was just cheering while the young Swifties were all smiles and giddy.
