Little Willow couldn't be happier to finally meet her baby brother.
Pink took to Instagram on Saturday to share an adorable photo of 5-year-old Willow holding newborn Jameson. The "Just Give Me a Reason" singer also thanked fans for their unconditional support.
"Happy New Year ? #newlove #newlife #newenergy #newhope #newday the harts thank you for your love ❤️ and we send it back to you in spades," the 37-year-old singer captioned the sweet pic.
"Jameson Moon Hart 12.26.16," she wrote alongside the image, posted on her account on Wednesday.
And, of course, Carey got in a little bonding time with his son as well.
