Pictures of Nicole Richie and Joel Madden With Sparrow and Harlow in LA

Nicole Richie held on tight to Sparrow while Joel Madden carried birthday girl Harlow around LA this afternoon. Harlow sported a sweet pink tutu and a crown for her big day, which the whole family celebrated with a star-studded party over the weekend. The proud parents attended a more grown-up event last night, when they stepped out to toast Nicole's new Lucky magazine cover. Nicole made a statement in bright eye shadow and a purple dress and talked about her plans for the new year, which apparently include a third novel.
