The Game of Thrones actress, who is usually recognised for her luscious blonde locks, has had half her head shaven.
Natalie seemed to draw even more attention to her new look by wearing an intricate earring accessory that covered most of her exposed ear.
Arriving to the Los Angeles affair, the 31-year-old star rocked her new hair as she posed for pictures on the red carpet with her series co-star Pedro Pascal.
Dressed in a floor-length white gown with black back detailing, Natalie flaunted her svelte figure and teamed the outfit with a black rectangular clutch.
Speaking about her new hair, Natalie revealed that she got a little help from the crew working on The Hunger Games: Mockingjay, in which she plays Cressida.
"The hair department of Mockingjay did it and I love it," she told E! News. "A little trepidation but I was excited."
