Kourtney Kardashian's two sons, Mason and Reign Disick, were both born on Dec. 14.

To celebrate them this year, the eldest Kardashian enlisted fiancé Travis Barker's help to set up an elf "concert" with lots of toys in attendance. On the drummer elf's drum kit are the words "ELF 182," a reference to Barker's band Blink-182, of which he is the drummer. Kardashian posted a photo of the sweet setup on her Instagram Story, to the soundtrack of the band's "All The Small Things."

Other members of the family rallied to celebrate Mason and Reign on their special day. Kris Jenner posted a collage featuring the two boys with the caption, "Happy birthday Mason and Reign!!! Can you believe these two were born on the exact same day?! I mean what are the chances???"
