WATCH: Kylie Kelce Belts Out Taylor Swift Song In Viral Video

A viral video shows Kylie Kelce , the wife of recently retired former Philadelphia Eagles center Jason Kelce , belting out a song by pop superstar Taylor Swift , the girlfriend of her brother-in-law, Kansas City Chiefs tight end Travis Kelce .

Kylie was seen singing Love Story as she held three large three beer pitchers while bartending an event for the Eagles Autism Foundation in Seal Isle City, New Jersey, in a video shared by the X account for Jason and Travis' New Heights podcast on Wednesday (June 26).

Jason was also seen dancing while bartending as the song Scatman by the late Scatman John played in a separate video .

Jason and Kylie were spotted attending Taylor's 'Eras Tour' over the weekend for the first time since she began dating Travis last year.

Jason, Kylie and Travis were in the VIP area of Wembley Stadium in London during multiple shows, as shown in videos shared online. A video posted by former NFL quarterback Chase Daniel showed the Kelce brothers dancing to ' Shake It Off ' in a private area that also included actors Tom Cruise , Liam Hemsworth and Hugh Grant , as well as actress Mila Kunis .

Another video showed both Travis and Kylie singing along to Swift's song ' Lover ,' which one fan claimed showed Kylie watching her brother-in-law "gush over Taylor."

A separate video showed Jason "very proudly" showing off a collection of friendship bracelets on his arm to his wife.

“It was insanely impressive,” Jason said on the latest episode of New Heights . “There's something, like obviously Taylor's an amazing singer-songwriter, but then to be able to go out there and be a performer at that level for how long she was up there for, like, three and a half hours, four hours?”

“The 22 hat? Dude, I've never cried at a f---ing concert and I was literally tearing up watching this little girl's entire … I'm about to tear up right now. It was f---ing so special,” he added.

“She got into it, man. It was awesome,” Travis said. “Every single show she does it. And she makes every show unique with the acoustic set.”

“That was my favorite part. It's just her, a guitar, and 90,000 people,” Jason responded. “And she's blending from one song to another ... Like, to be good in front of 9,000 people with just that, I think you have to be amazing. And you have to, one, have great songs and great lyrics, which she obviously has written and made. And then two, be able to perform those seamlessly on the spot, nothing else to hide it, just that was the highlight of the evening for me.”

Travis and Taylor went public with their relationship last September when the singer was seen with the tight end's mother, Donna , in a VIP suite at Arrowhead Stadium during the Chiefs' blowout win against the Chicago Bears, the first time she attended one of his games following relationship rumors. The three-time Super Bowl champion famously revealed that he attempted to give Swift a friendship bracelet with his phone number when he attended her concert at Arrowhead Stadium prior to their relationship last summer.

Swift later said that Kelce "very adorably put me on blast" when he acknowledged the situation on his New Heights podcast , which she said "was metal as hell" while being featured as Time Magazine 's 'Person of the Year' in December 2023.
