Pictures of Natalie Portman and Darren Aronofsky at Black Swan Lunch

Natalie Portman's cute striped sweater dress covered up her growing pregnancy belly as she posed with her Black Swan director, Darren Aronofsky, at an event in his honor in NYC this afternoon. She just returned to the East Coast following a stay in LA, where she picked up a SAG award and attended a pre-Oscars luncheon. Natalie also made time to go hiking with friends in the sunny weather, though now she's back to chilly walks in the Big Apple with her fiancé, Benjamin Millepied. She'll soon return to the West Coast for the Oscars, which are on Feb. 27 — don't forget to fill out BuzzSugar's ballot for a chance to win a Samsung TV!
