Travis and Jason Kelce are heading into the holidays with high spirits thanks to Taylor Swift’s fans.

“The Kelce duet reached No. 1 on iTunes,” Jason, 36, said on the Wednesday, November 22, episode of his and Travis’ “New Heights” podcast. “That’s right, ‘Fairytale of Philadelphia,’ our song from the new Christmas album debuted at No. 1 on the iTunes chart. That’s right, we are officially rock stars.”

For the Philadelphia Eagles’ upcoming holiday CD, A Philly Special Christmas Special, which will benefit numerous organizations, the NFL brothers collaborated to record “Fairytale of Philadelphia.” After the song’s November 15 release, it peaked at No. 8 on the Apple Music charts. However, Jason attributes the song’s success to Swift’s 33-year-old fan base, which helped the song reach No. 1.

“Aside from [‘New Heights’ fans] the 92 percenters, we owe a big thanks to one group in particular, and that’s the Swifties, because the Swifties came out,” he said. “I tweeted once it reached eight, and I received about eighty-five replies from Swifties worldwide asking, ‘Oh, you think eight is good?’” They said, “We’re taking this to No. 1,” and it was. It’s a strong group, a strong collection of individuals.

Travis went on to praise Swift, to whom he was first linked in September, and her fan base for their support. “Thanks, Taylor. [We] appreciate you, and thank you to the Swifties,” he said on the podcast. “Thank you.”

In addition to the brothers’ duet, A Philly Special Christmas Special will also feature collabs with Patti LaBelle, Amos Lee, The Hooters’ Eric Bazilian and Rob Hyman and members of The War on Drugs and The Silver Ages Choir.

Many fans have their fingers crossed that Swift will make an appearance on the album as her romance with Travis heats up. “Will taylor be on it now too,” one social media user commented on the album’s official Instagram account earlier this month, to which the account replied, “We love a Christmas miracle 🥹.”

Other Swifties believe the singer is featured on the album’s cover, which includes Peanuts-inspired cartoons. “The back cover is filled with Philly legends and some of your favorite faces,” the album’s Instagram account captioned a photo of the artwork. “Can you name everyone who came to see the show? .”

Swift has seen numerous of Travis’ Kansas City Chiefs games since they started dating, but because of a rescheduled concert in Rio de Janeiro, she was unable to watch him take on Jason and the Eagles in the highly anticipated Super Bowl LVII rematch on Monday, November 20.
