Kim Kardashian joined sister Kourtney and her son, Mason, yesterday to film Kourtney and Khloe Take Miami in Florida. The girls started the morning in front of the camera while shopping for Maseratis. Mason was decked out in a little blue outfit for the trip to the car dealership, after getting equally colorful on Wednesday when he donned green to celebrate St. Patrick's Day. Kim later had time to fit in a trip to the gym, and this morning she was right back to work for a promotional appearance at a Walgreens in a skirt and sky-high heels.
