Natalie Portman is working her butt off!
The actress appeared on The Late Show with David Letterman to promote Thor: The Dark World along with co-star Kat Dennings, and then was whisked off to appear at a screening for the movie at the Crosby Street Hotel in NYC on Wednesday.
We guess this slightly makes up for her missing the film's Hollywood premiere!
Natalie of course turned to Christian Dior for her clothing needs, wearing a black and white A-line dress with high-low hem to chat with Letterman.
Very Audrey Hepburn!
To match the simple aesthetic of the frock, she chose low-key accessories, including Dior slingback pumps and Harry Winston diamond earrings.
At the screening later that evening, Natalie worked a more modern vibe with a beaded Dior strapless top and black slacks.
We commend her for navigating between these two opposite looks so flawlessly!
