Thursday night kicked off with a dinner feting Rachel Zoe's first tome, "Style: A to Zoe," at Socialista. The celebrity stylist introduced her proud parents to friends including her hostess Margherita Missoni, Angela Lindvall, Stavros Niarchos, Tatiana Santo Domingo, Pierre Casiraghi, Liya Kebede, Brian Atwood and Diane Kruger, fresh off the plane from Venice. The dinner capped off a busy day for Demi Moore, who has been keeping a schedule as jam-packed as any editor with shows, lunches and parties. "I'm just glad there's something for me to do," said Moore, whose husband, Ashton Kutcher, is shooting a film in the city. "Though I do wish I could just slip in and watch, unnoticed."
Meanwhile, the crew at Purple magazine was hosting a dinner at Freeman's, with Ellen von Unwerth, Leelee Sobieski, Chiara Clemente and co-hosts Eric Villency and Julia Restoin-Roitfeld, who said she won't be at the shows. "I just started my new job" at Baron & Baron Inc., she said. "I want them to think I take it seriously."
After dinner, most guests headed uptown to Alexander Wang's after party in a Chelsea warehouse space, where Mischa Barton, clad in a long silver gown, stopped by to say hello after presenting at Fashion Rocks.
Meanwhile, the rest of the CBS special's stars headed to the Rainbow Room for the official after party, including Barton's friend Nicole Richie. Usher held court in a corner VIP section, receiving well-wishers congratulating him on his recent wedding to Tameka Foster, while Mary J. Blige raved about her "Entourage" cameo with the evening's host, Jeremy Piven: "That's my man," she said. "I think I made a real friend."
