Did Condé Nast's Jonathan Newhouse make a funny? Going by these pics from last night's launch of the new YSL pop-up shop in Dover Street Market, I'd say it must have been a good one to make Naomi Campbell crack up like that. Either way, Stefano Pilati unveiled his baby, Edition 24, with a glam cocktail party that drew the likes of Erin O'Connor, Hofit Golan, and Claudia Schiffer. Which begs the question... are Claudia and Naomi operating as a team these days? They seem to be popping up everywhere together.
