Mariah Carey and boyfriend James Packer hit the shops in Aspen, on Saturday, as they took their romance 8000 feet high!

The diva just wrapped her All I Want For Christmas Is You concert series in New York and headed west for her annual Colorado trip. The media magnate was along for the ride and trailed a few steps behind Mariah as she navigated the snowy streets.

Carey posted this sweet snap in front of the couple's Christmas tree at their mountain-high retreat. We're not sure which looks more awesome ... the ski chalet or Mariah!
