Offering a brief peek of her newborn daughter, Nicole Richie was spotted doing her ‘mommy’ thing by taking baby Harlow to a friend’s kiddie party in Beverly Hills yesterday.

The “Simple Life” celebutante looked pretty calm and casual in a grey v-neck shirt and black stretch pants with her usual oversized black sunglasses.

Kids’ parties aside, Nicole seems to be doing well at balancing her newfound motherhood with her newfound career - jewelry design.

She told press, “Everyone’s been really mellow and able to work around my schedule. If I need to go feed the baby, I do it.”
