Just when you needed a new Real Housewife to shake things up in the Hamptons, the Manzo sisters arrive. Caroline (left) and Dina (right) of "The Real Housewives of New Jersey" ate Friday night at Lily Pond's Hamptons Social Series party in East Hampton. They were joined by those see-them-everywhere cast members of "The Real Housewives of New York City," Bridgehampton's Jill Zarin and Southampton's Ramona Singer. Also at the Vision Vodka-sponsored event to salute St. Jude's was polo star Nic Roldan.
