The pair held their bundle of joy together as they smiled for the camera, the new mom glowing in red, while dad opted for a conservative grey sweater – and Gunner looked tranquil in a "Oh what Fun!" titled red sweater, and little baby booties.
Friday Montag took to her Instagram to post a cute pic of her and the new family, writing:
"Christmas is my favorite time of year! So blessed to have @gunnerpratt to share all the new traditions and memories! All I want for Christmas is my baby! 🎄 Gunner looks very amused by his parents selfies 😂"
Gunner has even met Santa!
The new baby boy came into this world a month before the couple celebrated their 9th wedding anniversary. The two first made headlines on the MTV reality hit "The Hills," back in 2007.
