Say hello to a new member of the Hamptons social set: Vince Shlomi, the man better known as the Vince the ShamWow guy, who, much to the surprise of those in attendance, put in an appearance at the Mercedes-Benz Polo Challenge at Blue Star Jets Field this past weekend. Shlomi says he's here in New York because "branching out from infomercials" with some sort of "movie project," and he also plans to design "some swimwear lines" with his new business partner, model Courtney Bingham.

The 2009 Mercedes-Benz Polo Challenge held its inaugural match at the Bridgehampton Polo Club on Saturday. Polo heartthrob Nacho Figueras, Chace Crawford, chef Marcus Samuelsson, Kyle MacLachlan and Desiree Gruber, Star Jones and boyfriend Herb Wilson, and a handful of reality TV personalities (Jill Zarin, PC Peterson, Kourtney Kardashian) turned out for the action. Cityfile's roving correspondent Douglas Marshall took a few minutes to catch up with Beth Ostrosky, who turned 37 last week but gets a gold star for still fitting into her short shorts from high school.
