Nicole Richie debuted her limited-edition line for Macy's in NYC yesterday. She showed up at the brand's Herald Square location to pose alongside models after doing press in the morning. Nicole swung by GMA to talk about the collection. Nicole also revealed that her busy schedule as a working mom had her returning to LA just a few days ago, between East Coast visits, to celebrate her son Sparrow's third birthday. While back in California over the weekend, Nicole attended Macy's Glamorama event with her husband, Joel Madden. The couple showed PDA when Nicole wasn't snapping pictures alongside Robin Thicke, who performed that evening.
