Nicole Richie joined Emma Roberts, Demi Moore, and Rachel Zoe to check out Ferragamo's Spring runway collection at a VIP dinner hosted by Harper's Bazaar at LA's Chateau Marmont last night. Rachel made the rounds with her husband, Rodger Berman, by her side, saying hello Tobey Maguire's wife, Jennifer Meyer; host Jacqui Getty; and more. Demi showed up solo, sporting a sexy black dress with knee-high boots, after stopping by the Matt Damon-hosted episode of Jimmy Kimmel Live. Emma Roberts, meanwhile, mingled with pal Gia Coppola. It was a busy night for Nicole, as well, who was on double duty after also attending the Elle Women in Television event.
