The 35-year-old actress told ET via a statement on Saturday that she would be skipping both the Independent Spirit Awards and Oscars ceremonies, due to her pregnancy. Portman was nominated at both awards shows for her leading role in Jackie, a portrait of Jacqueline Kennedy in the days surrounding her husband's assassination.
When ET caught up with Portman last month at the Screen Actors Guild Awards, she revealed she had yet to pick out a name for the new baby.
"You got to meet a baby before [you choose a name]," she explained at the time. "Gotta meet the baby and then figure it out."
