For the premiere of My Week With Marilyn at the 49th Annual New York Film Festival on Sunday it was only natural that star Michelle Williams would honor another 50s icon, Christian Dior, and RadarOnline.com has all the stunning photos from the glamorous night.

The actress, who plays Marilyn in the film that focuses on her troubled time while filming 1957′s The Prince and the Showgirl opposite Laurence Olivier, was an ethereal sight in a flowing nude gown at the Dior prescreening cocktail party at the Hudson Hotel in Manhattan.

Harvey Weinstein, Zac Posen, Coco Rochas and Gina Gershon all joined Williams to celebrate the biggest film of her career, which is executive produced by Bob and Harvey Weinstein and directed by Simon Curtis.

Gwyneth Paltrow and Chris Martin make it a point not to be photographed together, often fueling erroneous speculation that the couple is on the outs, but on Thursday the married superstars were finally spotted together along with their adorable little children.

The gorgeous and rich family flew into Manhattan by helicopter, and mom and dad happily carryied kids and toys around.
