Nicole Richie went vintage for a colorful new spread in the March edition of Harper's Bazaar Russia. She shared a behind-the-scenes photo of her and her hairstylist, Ken Paves, as they styled and shot the pop-art-inspired images last month. It's Nicole's second big cover since the beginning of the year, as she also graced Lucky's February issue. Nicole's busy modeling and promoting her Winter Kate and House of Harlow 1960 collections, but the mother of two has nonetheless been hanging out close to home with Harlow and Sparrow and focusing on gym time. Still, she stepped out looking ready for another closeup yesterday as she left a friend's house.
