Mariah Carey Wears Bikini To Walk Her Dog In Aspen

When you're Mariah Carey, you have your own set of traditions — like walking your dog in a teeny-tiny bathing suit.

The singer, who is currently on vacation with her cute 2-year-old twins and hubby Nick Cannon in Aspen, posted a revealing photo of herself on Instagram wearing a red-hot bikini and walking her dog in the snow.

The "All I Want For Christmas" singer said it was "just a tradition," which is hard to imagine, considering Aspen temperatures are currently hovering around -9°C at night. A tradition of looking smoking hot in the snow? That works.

And red certainly seems to be the star's favourite colour. Carey was also snapped wearing the same bikini, a silky red robe and furry red heels in front of a Christmas tree.

While she's enjoying the holiday season, the star also posted this adorable picture of her and Monroe and Moroccan warming up in the hot tub.
