Jason Kelce Joined by Wife Kylie, Pete Davidson and More for Holiday Party: ‘Everyone Was Having a Blast’ (Exclusive Source)

Jason Kelce is getting in the Christmas spirit!

The retired NFL star, 37, hosted a holiday party on Friday, Dec. 13 in honor of his annual Philadelphia-themed holiday album, A Philly Special Christmas Party.

At the event was Kelce’s wife, Kylie Kelce — who is currently pregnant and expecting the couple’s fourth baby. (The couple is already parents to daughters Wyatt, 5, Elliotte, 3, and Bennett, 21 months.)

Also in attendance was Pete Davidson, who “went with a couple of friends and got onstage with Jason and Eagles’ Jordan Mailata to perform,” an insider tells PEOPLE, adding of the comedian, “Pete seems like he’s doing great.”

“Everyone was having a blast,” the source continues.

Kelce’s Christmas album, which was released on Nov. 22, marks the third time the athlete has released a holiday-themed LP.

The 12-track album features covers of songs, including “Last Christmas,” “Feliz Navidad,” and “Sleigh Ride,” as well as three original songs.

Special guests are also involved with the project, such as Kelce’s wife, his brother Travis Kelce, Boyz II Men and Stevie Nicks.

“The legendary Stevie Nicks came on and did a duet with me,” Kelce previously said on the Oct. 30, episode of the New Heights with Jason and Travis Kelce podcast of his collab with the music icon. “Which in itself is, like, pretty crazy to actually be on a track with Stevie Nicks. I mean, absolutely unreal.”
