The Academy Award winner, who is expecting her second child with husband Benjamin Millepied, flew into LAX on Monday after promoting her upcoming films around the world. The second time mom-to-be dressed her growing baby bump in a chic and comfortable neutral ensemble for her journey. The centerpiece? A structured knee-length tan trench coat, which she wore over a pair of white cropped straight-cut trousers that hit right above her ankles. The Black Swan star finished off her look with Jackie O-appropriate oversize cat-eye sunglasses and neutral peep-toe sandals with ankle straps. For the trip, the actress pulled her dark hair back into a low, sleek bun.
