Kylie Kelce proves to be the ultimate Eagles fan with perfect Cowboys dis at a Philadelphia inspired bar in London

Jason, Kylie, and Travis Kelce had quite an eventful time in London last weekend.

And while a lot of the focus was on Travis making his Eras Tour debut, Kylie Kelce did one thing that proved her loyalty to her favorite team.

Philadelphia Eagles fans already love Kylie, with her husband Jason having spent his entire career with the franchise. And with that, she has made it clear that she refuses to wear another team's apparel. Even when the Eagles were out of the playoffs and the Chiefs were making their run, all the Kelce's attended the games. But Kylie refused to wear Kansas City gear. Instead, she would wear red, but never anything with the Chiefs logo on it.

And during their trip in London, she took her fandom one step further.

The two brothers filmed their most recent episode of the New Heights podcast in London and Kylie came along. More specifically, they did it at Passyunk Avenue , a Philadelphia inspired dive bar.

And when they were leaving, Kylie gave the manager the perfect parting gift.

"Our bar has a bit of a tradition,” JP Teti, a Philadelphia native and founder of Passyunk Avenue, told PEOPLE. “Everything you see on the walls has been donated by people over time, so it's like a collection of other people's junk that proudly hangs in our bar."

"One thing that has happened over time is people will take American dollar bills and write messages in Sharpies and stick them all over the venue," Teti added. "As Jason and Kylie were getting ready to leave, she was like, 'Jason give me a bill, I want to write a message and leave it behind,’ and Jason said, 'All I've got is a 100,' so Jason takes out a 100 and she says, 'Okay fine I’m writing on a 100 then, that's what we're doing.' The message was, 'F--- Dallas, Go Birds and Go Cabrini,' where she went to college.”

Kylie just couldn't miss an opportunity to take a dig at the Dallas Cowboys.

“She insisted on standing on a chair and pinning it at the highest part of the venue herself and I just kept thinking, ‘Please don’t fall,” Passyunk Avenue manager Jessi Riley said. “She said, ‘If you’re worried about liability just look away!’”

And Riley's reaction to meeting Kylie says everything: "She’s so cool, very down to earth."

Jason Kelce and his Friendship Bracelets

The Philadelphia Eagles center and his wife arrived and immediately joined in on the festivities. Fans flocked near the VIP tent, hoping to catch sight of the power couple and potentially take part in a tradition at the Eras Tour.

The two started sharing and trading friendship bracelets with many of the fans in attendance.

Jason even had a whole arm full of bracelets ready to go.

He was even so proud to show Kylie how many he had gotten.
