Jason Kelce joked that Taylor Swift’s fanbase, the Swifties, “completely f–ked’ the “integrity” of his and his brother Travis’ “New Heights” NFL bracket competition.

Travis, however, claimed the Philadelphia Eagles center manipulated results by involving the Buffalo Bills fans, Bills Mafia.

“I only campaigned for teams that were underrepresented. I just wanted voter turnout,” Jason explained on their podcast Thursday morning.

“The Swifties have this unrealistic infatuation with the Chiefs and Travis Kelce.”

Jason, 36, further explained that Swifties were “only voting based on their love” for Travis and “not on their love for the team name.”

“It’s just ridiculous that you’re throwing everything on the Swities,” the Kansas City Chiefs tight end said.

The bracket ended with the Eagles losing to the Minnesota Vikings, and once again Jason blamed the Swifties.

“[The Swifties] don’t understand how politics work, so they got really accusational of me manipulating votes, so they voted against me,” Jason admitted.

Little does Jason know that the Swifties are going to come for him now that he’s criticized them, but as long as the “Cruel Summer” star stands by the Kelce brothers’ side, he’ll be fine.

Jason will have a chance to reunite with Swift, 34, at the 2024 Super Bowl this weekend, where she’s expected to support Travis as his team takes on the San Francisco 49ers in Las Vegas following a performance in Tokyo.
