THE GOLDBERG VARIATIONS: Gangsters and their molls, flapper girls and newsboys made the scene Saturday night at Morton’s when Amanda Goldberg celebrated her 30th birthday in Twenties style. Robert Downey Jr. and fiancée, Susan Levin, China Chow, Lisa Marie, Christopher Walken, Kelly Lynch, Mitch Glazer and Mickey Rourke partook in the period party favors (feather boas, cigarette holders and faux-diamond rings), while the birthday girl flitted about in a Twenties French tunic from Lily et Cie. “I’m in heaven because I’m in a ‘Great Gatsby’ mode these days,” said Shiva Rose McDermott, who has been rereading the Fitzgerald novel and had slipped into her vintage dress in the car. By the time the soiree wound down at 1:30 a.m., the crowd was boogie-ing to 50 Cent. The hostess sighed, “I only wanted Twenties music, but I got the sense people needed to hear some songs they recognized.”
TROYING IT ON: She may not be the face that launched a thousand ships, but Diane Kruger, who plays Helen — yes, that Helen — in the new film “Troy” is the face that launched Nicolas Ghesquière’s Balenciaga advertising campaign three years ago. Now that “Troy” is set for release on May 14, the pair have been making the New York rounds. Ghesquière squired Kruger to the Metropolitan Museum’s Costume Institute gala Monday night, where she wore a champagne silk Balenciaga gown modeled after a 1932 house original; the following evening, the designer threw the actress a dinner in the Hudson Hotel penthouse. Kruger, who has two more films set for release this year, said she’ll be wearing Balenciaga for all the television appearances she makes in conjunction with “Troy.” As for the skimpy outfits Brad Pitt wears in the film, the actress quipped: “It was nice to have the ladies wearing the long dresses and the men wearing the short skirts for a change.”
Also on Tuesday in the Meatpacking District, Stella McCartney hosted a cocktail party at her store that brought out Sandra Bernhard, Moby, Renee Rockefeller and Liv Tyler, who spent much of the evening trying on clothes in the dressing room. Whereas Ghesquière had a full raw bar, McCartney kept the options vegetarian with black bean quesadillas, veggie dogs and Tofuti Cuties.
