Mariah Carey certainly knows how to heat things up for the holidays!

The 43-year-old singer posted some sexy photos on Instagram before hopping in the hot tub with hubby Nick Cannon and their adorable twins, and keep in mind she's in Aspen, where the temps are in the teens overnight!

"Warming up for the hottub moments!" Mariah wrote, later adding, "It's just a tradition #aspen#coldyethot." Cold yet hot indeed!

Mariah also posted the adorable shot below with Monroe and Moroccan and wrote "Misty wonderland with dembabies!"


So cute!
