"It's just a tradition," the crooner wrote next to the picture. Carey is currently on vacation in the popular Colorado ski destination with twins Monroe and Moroccan, both 2. In another picture, the Grammy-winning singer, hugging both kids in a hot tub, shared with fans, "Misty wonderland with dembabies."
In a new interview with "Access Hollywood" last week, Carey shared that this holiday will be the first one involving presents for her kids with husband Nick Cannon. "We always do really fun tricky things for each other for Christmas, and this year, I'm just like, 'Let's make it about the babies,'" she shared.
"Now they see the tree and they light up. They're so excited; it's amazing for me to watch and to relive," she added.
Cannon's wife later shared a sultry photo of herself posing in front of a tree and wearing the same bikini with a matching silk bath robe and slippers while putting a finger to her lips. "Warming up for the hottub moments!" she wrote.
