Philadelphia Eagles Center Jason Kelce has asked his brother, Kansas City Chiefs tight end Travis Kelce, to help him sing a special duet for the second volume of the Philadelphia Eagles’ Christmas album, A Philly Special Christmas, writes Natasha Dye for People.

An NFL video shows Jason, 36, in the recording studio asking Travis, 34, to join him on the song.

“Yo Trav, we’re here recording the Christmas album, and the guys have an idea that maybe you could hop on. It’s like two people fighting, but then they really love each other,” Jason explains to his brother on the phone.

Kelce explained to his brother that the song fits in well with their relationship.

Travis’ response can’t be heard in the video, but Jason ends the call with “Glad you’re game. It’ll be fun.”

The duet will be released today and will be part of A Philly Special Christmas, available Dec. 1.  

The Eagles’ Christmas trio includes Jason, Jordan Mailata, and Lane Johnson. The album will also include a feature from Patti LaBelle.

Among the songs on the album is the NFL stars’ take on Mariah Carey’s Christmas classic, “All I Want for Christmas is You.”
