Kylie Jenner Turns Up the Heat in Aspen!

Kylie Jenner has made her way out to Aspen Colorado with a group of her friends and family on what seems to be an annual ski trip the reality tv star takes each year. This year, Kylie is turning the heat up at her vacation rental by wearing a very tiny black string bikini and posing in the outdoor hot tub.

The star showed off her rock hard abs and gave us all a little glimpse of her booty in the shiny black bikini before running into the home gym to pose in her bathrobe. See more photos of Kylie keeping warm in Aspen in the gallery!
