Less than 24 hours after walking the red carpet with pal Kate Moss at the Costume Institute gala on Monday night, Stella McCartney was on the opposite side of the country, hosting a cocktail and special screening of the Peter Sellers classic The Party at her West Hollywood boutique. The Tuesday-night garden party brought out a crowd that included Nicole Richie, Christian Louboutin, China Chow, Frankie Rayder, and Amber Valletta. "It's great to be back in L.A.," said McCartney. "I never have to pack much, because luckily I have the store." The consummate hostess made sure her tables were stocked with every treat imaginable, from Mentos to Marlboros, the latter courtesy of an old-fashioned cigarette girl. While many guests were thrilled with the mini grilled cheeses, others were happy just to catch up. "I met Stella when we were five or six and they came to stay with us," recalled Rashida Jones. "They were like the foreign fun, and we loved it." Charlize Theron added, "She's just such a lovely lady. We knew we were going have a good time."
