The 42-year-old Oscar winning actress looked carefree and relaxed, wearing her hair in relaxed waves and showing off the stunning designer gown. At one point, she pulled the multi-colored ensemble above her knees and danced in front of the cameras.

Between filming she covered up in a blue robe, as production staff rallied around. Portman appeared to nail her shoot as she threw herself into her work despite facing major problems in her 11-year marriage to Benjamin Millipied, due to cheating claims.
