Jason Kelce and Travis Kelce have recorded a Christmas song.
Titled Fairytale of Philadelphia, the duet is set to feature on the Philadelphia Eagles' upcoming holiday album, A Philly Special Christmas Special.
The album's official Instagram page posted a teaser clip of the song on Tuesday featuring the duo singing as claymation-style puppets.
"Philly, are we going to let a Chief steal the show? No way," read the caption. "But we are going to enjoy the newly reimagined single, Fairytale of Philadelphia by Jason & Travis Kelce."
Jason, 36, plays NFL for the Philadelphia Eagles, while his brother, Travis, 34, plays for rival team Kansas City Chiefs.
In a recent episode of the brothers' New Heights podcast, Travis revealed he hadn't yet listened to the final version of their collaboration.
"Dude I do not want to hear myself sing like that. I've got more of the rock voice," the Kansas City Chiefs tight end, who is currently dating pop star Taylor Swift, admitted.
The album would also feature Jason and his teammates Jordan Mailata and Lane Johnson's rendition of Mariah Carey's All I Want for Christmas Is You, which was released earlier this month.
Fairytale of Philadelphia is set for a 15 November release.
