Pop stars, supermodels, heiresses, and royals (from at least three different countries) all laced up their finest snow boots this weekend for the blowout wedding of Dasha Zhukova and Stavros Niarchos in oh-so-glam Swiss ski town, St. Moritz. The $6.5 million, days-long affair kicked off with a surprise ceremony on Friday (a day earlier than guests expected) at a special spot near the Olympaschanze ski jump, followed by a full-on Russian-themed fete straight out of a Tolstoy novel. And everyone who's anyone was there.
