Nicole Richie and her kids, Harlow and Sparrow, visited a friend in Hollywood yesterday. The trio coordinated with all-black ensembles, and Nicole and Sparrow took their matching one step further with similar hats. Joel Madden didn't join his family for the outing, since he's now on the road with Good Charlotte. Their Summer tour kicked off just last week in San Diego, and Joel shared some quality time with Sparrow and Harlow at a park before taking off. He'll be overseas with the band through August, which means Nicole will be busy with their little ones. She also has her designing duties to focus on, and she recently shared the House of Harlow Fall lookbook.
