Between making movies, working on her fitness, and schlepping school projects [1], Jennifer Garner [2] makes time for a good laugh. On Wednesday, the actress was spotted cracking up while walking down the street with a friend in LA. Jen stayed bundled up in a cozy jacket and running shoes as she made her way to her car. The night before Jen's giggly outing, her estranged husband Ben Affleck revealed their holiday plans [3] at a screening of his new crime drama, Live by Night, which he coproduced with Leonardo DiCaprio [4]. "I can tell you that we're going to do skiing in Montana with our family and Matt Damon [5]'s family and my brother [Casey Affleck [6]]'s family," he told ET. Ben also praised Jen for her parenting skills [7] — calling her "world's greatest mom" — and said of his three kids, "It's a joy to hang out with them."
