Kristin Cavallari is one hot mama!
The former star of "The Hills" has been making the promotion rounds this week -- and showing off her killer post-baby body everywhere she goes.
The reality star flaunted her legs at two different events yesterday, stepping out in a very pair of shimmery short shorts outside of NBC and wearing a red dress at the launch party for her Chinese Laundry by Kristin Cavallari shoe line.
At an event back in October, Cavallari revealed how she got back into pre-baby shape so easily -- check out the video below to find out:
