New York’s oldest and most beloved socialite, Zelda Kaplan, celebrated her 94th birthday with some late-hours clubbing at new lounge Entre Nous. She was toasted by a crowd the other night, including Richie Rich, New York Social Diary editor David Patrick Columbia, violinist Joshua Bell, singer Reni Lane, photographers Gideon Lewin and Bill Hueberger, celeb stylist Mia Morgan. Zelda told guests she still “parties till dawn” and “loves to be grandma to all the club owners.”
