Both supermodels and actors showed up at the Whitney Museum in NYC to check out the latest exhibit, Picasso and American Art. The crowd included celebs such as Stephanie Seymour, Michelle Williams, Emmy Rossum and Jimmy Fallon. Adorable Michelle looked fabulous in her little yellow number, but unfortunately Heath was nowhere in site. Stephanie Seymour pulled a Sharon Stone by wearing a see-through dress. Don't these women know the flashes will expose what they are not wearing underneath their outfits?

More pics including Piper Perabo, Helena Christensen, Leelee Sobieski, Uma Thurman and a very see-through Stephanie Seymour so
