Justin Bieber's son, Jack, channeled his inner Santa Claus while flying high above the clouds on Christmas Eve. Justin, who shares Jack, 16 months, with wife Hailey Bieber, shared rare photos of the little one dressed up as the Christmas figure via Instagram on Thursday, December 24, while on a private jet. In the snaps, Jack is wearing a red sweatshirt, gray sweatpants and a festive red beanie with a white puff ball reminiscent of Santa's iconic wardrobe. The toddler can be seen walking on the plane, holding onto plush, leather seats on the right.
