Pink and her husband, Carey Hart, welcomed their second child, son Jameson Moon Hart, on Dec. 26, and he's already in such good hands. The singer posted an adorable photo on Instagram on Saturday of her 5-year-old daughter, Willow, holding her new baby brother. "Happy New Year 🎆 #newlove #newlife #newenergy #newhope #newday the harts thank you for your love ❤️ and we send it back to you in spades," she wrote. Despite Jameson only being a few days old, we've already been treated to a few photos of him. In addition to sharing a close-up of his little face shortly after his arrival, Pink also posted a photo of Carey cradling their newest addition. We already can't wait for the family moments these four will share in 2017.
