Last night Hollywood traveled to NYC to help celebrate Cartier's "100th Anniversary in America" at their Fifth Avenue Mansion.  Stars including Kate Hudson, Jessica Biel and b.f. Justin Timberlake, Demi Moore, Anne Hathaway, Rachel Weisz, Eva Mendes all came dressed to impress.  We especially loved Kate Hudson's black cut out dress-whose style did you like best? 

Others party goers included Sir Elton John, Russell Simmons, Zac Posen, Phillip Lim, Martha Stewart, Susan Fales Hill, Cornelia Guest, Dayssi Olarte de Kanavos, Dr. Lisa Airan, Dylan Lauren, Graydon Carter, and Daniel Boulud.   More story and photos after the jump..

A bevy of models was also in attendance, such as Coco Rocha, Hillary Rhoda, Erin Fetherston, and Julie Henderson. The guest of honor, however,  was famed photographer Bruce Weber whose new book: "Cartier I Love You: 100 years in America" will be available in June (part of the proceeds go to charity.)  Meanwhile Cartier is also marking its' century landmark with an exhibit: "Cartier: 100 Years of Passion and Free Spirit in America," currently on display at the flagship store. The presentation features (naturally) 100 Cartier design creations, including many from private collections, and will be on view in New York until May 21 before traveling on to Beverly Hills.  So, if you're having a bit of a Breakfast at Tiffany's moment, go take a peek at some of their beautiful baubles while you still can.
