The Hiltons are definitely enjoying their family vacation in Aspen, Colorado.

Nicky and her mom Kathy ditched the slopes for the day and bundled up for an afternoon shopping trip. No wonder the Hilton girls are hot ... look at their stunning mom!

Paris has been focusing less time on shopping and more on skiing. The heiress recently Tweeted:

    "Love skiing down the mountain blasting @DJAfrojack @DavidGuetta & @Kaskade on my Ipod. It's like clubbing in the snow;) #RavingOnTheSlopes."


Nothing like spending Christmas in the snow. Life is good for the Hiltons!
