The 35-year-old actress, who is expecting her second child with husband Benjamin Millepied, is featured on the cover of Vanity Fair's Hollywood Issue, chic in a powder pink off-the-shoulder gown alongside Emma Stone, Greta Gerwig, Amy Adams, Aja Naomi King, Ruth Negga, Lupita Nyong'o, Janelle Monae, Dakota Johnson and sisters Elle and Dakota Fanning.
The brunette beauty was nominated for her third Oscar earlier this week, this time for Best Actress for her portrayal of former first lady Jackie Kennedy in Jackie. Portman celebrated the exciting news by going for a hike in Los Angeles, looking comfy and cute in a striped maternity top and sweats. (See the pics HERE!)
"It was very scary to take on somebody that people know so well -- the way she looked, the way she spoke, the way she moved," she confessed. "You have to overcome that hurdle before you can even get people to sign on to emotionally empathize with you."
