Harlow Winter Kate Madden isn't even three months old, but Nicole Richie already has another baby -- a jewelry line. "It's all costume jewelry," Nicole tells People. "I like to play with jewelry and mix and match." But the new mom says that working isn't impeding on her time with Harlow. "Everyone's been really mellow and able to work around my schedule," Nicole says. "If I need to go feed the baby, I do it." Let's hope she's as good with balancing when she introduces her infant and children's wear lines later this year and possibly launches a fragrance.
