Jason Kelce is a big supporter of brother Travis Kelce’s love story with Taylor Swift — but admits the public interest in the new couple is “a lot.”

“It’s certainly been weird, the level that it is now,” he told NBC Sports on Sunday night. “On one hand, I’m happy for my brother that he seems to be in a relationship that he’s excited about, that he is genuine about. But there’s another end of it where it’s like, ‘Man, this is a lot.’”

The Philadelphia Eagles center, 35, continued, “There’s paparazzi talking about him fueling his car before the game today and I’m like, ‘Is that really necessary information to share?’”

“This is another level of stardom that typically football players don’t deal with,” he added.

As long as Travis, 34, is safe, however, Jason is “happy” for his little brother amid his budding romance with the pop star, 33.

“And so on one hand, really, really happy for my brother and where he’s at in his current situation with Taylor but on the other hand, there’s some, I think, alarms sometimes with how you know, over-in-pursuit people can be,” he told NBC Sports.

“Overall, he can deal with some of this,” he added. “As long as it’s not, you know, becoming a threat to his safety and things like that.”

On Monday, Jason mentioned Swift again, this time on the Today show. The center appeared on the show with fellow Eagles linemen Lane Johnson and Jordan Mailata to talk about their second Christmas album, a now-annual charity project.

While discussing the record, which features a Patti LaBelle duet, Kelce shared that he would not be opposed to a Swift appearance on the holiday album next year.

“Maybe, not this one, not this time around,” Jason, 35, said after Today co-host Sheinelle Jones asked about the possibility of a holiday collaboration with the Midnights songstress.

“That would be pretty incredible,” he added. “Maybe in the future.”

On Sunday, Travis and the Kansas City Chiefs won their fourth game with the “Love Story” singer in attendance, prompting head coach Andy Reid to praise the pop star’s seemingly positive influence.

“Kelce is getting better with time,” Reid said during a press conference shared on social media, adding: “Taylor can stay around all she wants.”

Reid’s comments after the Los Angeles Chargers defeat marked the second time he has mentioned Swift amid her new relationship with his star tight end. A week earlier, Reid, who used to coach the Eagles — both Jason’s team and Swift’s hometown team — talked about knowing the pop star’s dad.

“I knew her from Philadelphia; her dad was a big NFL fan, so I had met her when she was real young, and her dad,” he explained before jokingly taking credit for orchestrating the internet’s favorite new romance.

“I joked about setting Kelce up, and, you know, I’m just saying!” the Chiefs head coach said.

He added, “She’s a good girl, she’s into it, we’re glad she’s here.”
