BODY DOUBLE: Kelly Rutherford and Howard Stern’s wife, Beth Ostrosky, turned up at Nicole Miller in the same white minidress. Nonplussed about the who-wore-it-best-photo-op, Ostrosky shrugged, “It was a nice surprise. Kelly is a beautiful woman. I hope I measure up.”
As for whether her Shock Jock man will replace Simon Cowell on “American Idol,” Ostrosky said, “He’s just having fun with the idea right now. As someone who gets to watch the show with him every week, I can tell you he is hysterical and brutally honest.”
Look for Rutherford at Tory Burch, Isaac Mizrahi and Catherine Malandrino — the latter’s son goes to the same school as her children.
