Jason Kelce explains how Travis Kelce’s relationship with Taylor Swift has impacted his younger brother and changed him for the better.

Jason Kelce can thank Travis Kelce’s cheer captain for his growth.

The They Call it Late Night host admitted that he’s seen quite a change in his younger brother since he and Taylor Swift started dating.

“It’s been staggering honestly,” Jason, 37, said in an interview on the Feb. 18 episode of the Fitz & Whit podcast. “One of the things I love so much about Travis is that he never grew up. He was like Peter Pan and the Lost Boys.”

Travis, 35, began his relationship with Taylor, also 35, in 2023, and according to Jason—who shares daughters Wyatt, 5, Bennett, 3, and Elliotte, 23 months, and is expecting his fourth with pregnant wife Kylie Kelce—their love has been a positive thing for the Kansas City Chiefs star.

“I think that sometimes you get people in your life that maybe get that out of you and that’s a good thing,” Jason said. “Trav he is growing up. He still got that youthful enthusiasm. I think he’ll always have that, that’s just part of his personality and I think it’s one of the reasons that every teammate has loved playing with him.”

“Anyone that’s ever met Trav, you can’t help but to love the guy,” he added. “He’s a free spirit in the best possible way.”

The Kelce family, which also includes Jason and Travis’ parents Donna Kelce and Ed Kelce, have each shared sweet moments with the Grammy winner.

Kylie recently recounted the “great” first meeting she had with the “Blank Space” singer when they watched the Kansas City Chiefs face-off against the Buffalo Bills in January 2024.

“People are deeply disturbed by this,” the Not Gonna Lie host noted on Call Her Daddy earlier this month. “There was all of this stuff leading up to it about, ‘Why haven’t they met? They’re avoiding each other!’

“I’m not avoiding anyone,” she continued. “I’m more than happy to meet anyone. Especially someone that Travis is dating.”
