Heidi Klum Wears Lingerie on Freezing Balcony in Sensual Instagram Video

Heidi Klum ain’t phased by the cold … stripping down to just red lace lingerie and stretching on a frosty balcony in a video she posted to Instagram.

The model and television star posted a clip to her Instagram Saturday … running her fingers through her messy, dirty blonde hair out on the balcony — with the top of her backside showing in a red thong.

After doing a few stretches, Heidi turns, grabs a big handful of snow and throws it just above the camera … possibly at husband Tom Kaulitz, who we know is gallivanting around Aspen with her.

In her caption, Heidi asks her fans if they have a tradition for New Year’s … before admitting she’s a sucker for red lace.

As you may know … Heidi’s an active skier — sharing clips where she’s carving up the slopes while hanging out in the popular celeb holiday spot.

Kaulitz — Heidi’s husband of five years — loves winter sports too … joining his better half on their skiing trips engaging in a little PDA while soaking up the brisk mountain air.
