Natalie Portman shows off massive baby bump at 'Jackie' screening

Natalie Portman continued to show off her ever-growing baby bump this week.

At a screening of her new film, "Jackie," in Washington, DC, Portman rocked the tight, long-sleeved gray Isabella Oliver Nextor Dress that flaunted her gorgeous curves and massive baby bump.

The actress is expecting her second child with husband, Benjamin Millepied, and they already have a five-year-old son, Aleph Portman-Millepied, together.

"Jackie," which opens today, has been receiving stellar reviews from critics just as the Oscar race begins to really heats up heading into the beginning of awards season. Specifically, Portman herself has been getting Oscar buzz for her portrayal of Jacqueline Kennedy in the wake of her husband, President John F. Kennedy's, assassination.

Portman has been making the rounds to support the film ever since it premiered at Cannes earlier this year and, in turn, she has been showing off her steadily-growing baby bump in glamorous frocks for months now.

One big question looms as the countdown to February's Academy Awards continues to tick: Will Portman give birth to her second child before or after Hollywood's biggest night? The star was memorably pregnant when she accepted her first Oscar for Best Actress in "Black Swan" back in 2010.
