A radiant Natalie Portman appeared in L.A. Tuesday night for the premiere of her film "No Strings Attached," co-starring Ashton Kutcher. Portman told "Extra" it's been a little difficult trying to wrap her head around the fact that she's pregnant and engaged.

"It's hard to really understand the enormity of everything that's going on," she said.

Keeping her baby bump hidden on the red carpet under a black Vena Cava dress, Portman said the dress "happens to be perfect for a larger bod, haha!"

Nominated for a Golden Globe for Best Actress for her role in "Black Swan," Natalie said picking the perfect dress for Sunday's ceremonies shouldn't be a problem. "I'm just like, don't let me not be in anything I will trip in."

Catch Natalie in "No Strings Attached" when it hits theaters January 21, and watch the Golden Globes this Sunday, January 16 at 5 PM PST on NBC.
