Alessandra Ambrosio and her fiancé, Jamie Mazur, took their kids, Anja and Noah, for a shopping trip and playdate in LA yesterday. Alessandra held on to her baby son while 4-year-old Anja walked alongside her dad. Alessandra is back home after spending the weekend in Park City, UT, for the Sundance Film Festival. She shared photos on her Twitter account while hitting the slopes on her snowboard and keeping warm with a cup of hot cocoa. Before her trip to the snow, Alessandra was on the beach in Miami for a Victoria's Secret photo shoot. She sported sexy lingerie and a pair of angel wings for the camera and even got a foot rub from a friend when she was finished posing.
