Scott Swift was known to be an Eagles fan before his daughter started dating Chiefs player Travis Kelce.

It looks like Taylor Swift may not be the only mastermind among the Swift and Kelce families.

Kylie Kelce, wife of Philadelphia Eagles player Jason Kelce and sister-in-law to Taylor’s boyfriend Travis Kelce, recently played along with a Swiftie theory that she was behind the Eagles lanyard sported by Taylor’s dad Scott Swift during Super Bowl LVIII, which notably replaced the Chiefs lanyard he’s recently been seen sporting.

While Scott, 71, is a Pennsylvania native, he seems to have turned into quite the Kansas City fan ever since Taylor, 34, began dating the guy on the Chiefs—but it looks like Kylie, a die-hard Eagles supporter, might be getting through to him.

In TikTok footage from the Super Bowl on Feb. 11, one Swiftie zoomed in on the Eagles-branded lanyard around Scott’s neck, even though the rest of his outfit featured Chiefs gear.

“kylie and jason…i’m onto you,” the video’s creator, Bethenny Pendleton wrote alongside the pics, insinuating that the couple may have had something to do with Scott’s new Eagles swag.

And Kylie all but confirmed the theory when she commented on the post, writing “Have you ever seen the grinch smile gif?”

Judging by her reference to the classic up-to-no-good smile from the famous cartoon character, Kylie doesn’t seem to be denying that she and Jason could be responsible for Scott’s lanyard—but Scott, however, has previously insisted that he really doesn’t play favorites.

While being approached by reporters at LAX earlier this month, Scott was asked where his NFL team loyalties lie, to which he cleverly replied, “I’m a football fan—of all teams.”

Even Taylor grew up as an Eagles fan, and even includes a lyric about wearing an Eagles T-shirt in her song “Seven” off her folklore album—though it’s safe to say she is undoubtedly a Chiefs fan now, thanks to Travis, 34.

Perhaps Scott should follow in the footsteps of Jason and Travis’ mom Donna Kelce, who has been known to wear merch supporting both of her sons’ respective teams.
