The video, which was shared by X user @bjw007, shows Kelce walking up to the surprised a young fan, who was wearing his Kelly Green Eagles alternate jersey, before posing for a picture with him.

"Just wanna say a massive thank you to @JasonKelce if we did not already know it what a legend you are and for your wife to record it. We will be forever greatful for this interaction, even the shock it caused #newheightsshow #eagles @newheightshow #kelce #gobirds," the post stated.

Kelce and his wife, Kylie, went viral after being spotted attending Swift's 'Eras Tour' this past weekend for the first time since the pop superstar began dating Jason's brother, Kansas City Chiefs tight end Travis Kelce, 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.

Travis also made a surprise surprise appearance on stage during the final night of Swift's three 'Eras Tour' concerts in London.

Taylor and Travis initially went public with their relationship when she attended his game against the Chicago Bears at Arrowhead Stadium last September. 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 and Jason's New Heights podcast, which she said "was metal as hell" while being featured as Time Magazine's 'Person of the Year' in December 2023.
