Baby It's Cold Outside! Heidi Montag & Spencer Pratt Strip Down In Aspen

Heidi Montag and husband Spencer Pratt love a good photo opp so they couldn't resist stripping down for a hot tub dip despite the chilly temps in Aspen.

Heidi shows off her curves. The Hills star had her Size F breasts reduced because of health problems.

Bottom's up: Heidi and Spencer drank champagne in the hot tub.

In 2010, Heidi had 10 plastic surgeries in one day because she "felt really insecure."

Heidi and Spencer have been spending the holidays in her native Colorado.
