Leave it to Mariah Carey to find a way to show some serious skin amid major snowfall!

The 43-year-old mother of two put her bikini body on display this morning on Instagram, looking incredible in all red -- sporting a matching silk robe, bikini and heels as she posed in front of a giant Christmas tree.

In another snap, she's seen with twins Moroccan and Monroe in a hot tub.

The family is currently spending the holidays in Aspen, Colorado -- a tradition for Mariah and Nick Cannon.

In the most ridiculous pic from her bikini photo shoot though, she's seen walking one of her dogs outside in the snow ... in nothing but her two-piece!

FYI, it's currently only 17 degrees there right now. Hope it was a quick walk!
