For the first week of 2012! despite the chilly temps, Jennifer Aniston and Justin Theroux kept things hot in Colorado. A source tells Us Weekly the duo vacationed in a 13,300 square foot private residence in the Mountain Village outside the town of Telluride where they were first spotted Dec. 31.

“They had a group of friends [that left] Monday,” the source tells Us. “Justin and Jen [stayed] until Thursday. They had a ski instructor every day.”

“[Jennifer] gets up [and] goes skiing,” adds the source. “Pretty much [she's] camped out at the house, keeping a low profile.”

Another source tells Us that Aniston, 42, and pal Chelsea Handler took a ski lesson together.
