Hamptons 4th, Russian-style

Russian billionaire bachelor Igor Sosin, who dropped $860,000 for a two-month summer rental in Southampton, threw a lavish July Fourth party to celebrate. Sosin packed his place on Ox Pasture Lane with wealthy Russians and beautiful models. Guests included Russian-American real-estate attorney Edward Mermelstein and all Sosin’s neighbors “to avoid noise complaints.” A source said, “any unaccompanied male was assigned a model to escort them around the party.” Sosin, who owns Russia’s equivalents of Home Depot and Petco, was accompanied by a “beautiful redhead,” we’re told. The bash at the 12-bedroom mansion included fireworks and ended with guests jumping into the pools with Champagne bottles. Sosin wasn’t available for comment.
