The Black Swan actress made sure all eyes were on her as she sauntered down the red carpet in London's Leicester Square.
Natalie looked the picture of elegance in a full metallic skirt designed by Christian Dior which glimmered as she walked.
She let her traffic-stopping number do all the talking by adding a plain black knit featuring a large cut-out detail on the back.
The gorgeous brunette kept her make-up minimal, sporting taupe smoky eyes, pink glossy lips and and a coat of clear varnish on her nails.
Her locks were gathered into a simple wrap-over ponytail and she accessorised with diamond earrings and a statement watch.
Natalie - who plays scientist Jane Foster in the film - was joined by a host of celebs at the event, including The X Factor contestants and her hubby, dancer Benjamin Millepied.
The couple looked totally loved-up as they posed for the press, before heading inside the Odeon cinema to watch Natalie in action. Awww!
