After causing a red-carpet stir at the Oscars, secretly married couple Natalie Portman and Benjamin Millepied took their baby, Aleph, to A.O.C. in LA for a relaxed family dinner. “They were playing with the baby, holding him in the air, and people at the next table were cooing over him,” said a spy. “It was quite sweet. They left with the baby wrapped in a blanket.” The “Black Swan” star and the choreographer showed off “recycled platinum” wedding rings at the Oscars.
