Natalie Portman sported a black Givenchy ensemble with a plunging neckline down to her navel on Wednesday night.
The 38 year-old was out in support of her new film, Lucy In The Sky, in which she plays a determined, single-minded astronaut.
She turned heads arriving at the flick's Los Angeles premiere, showing off her Givenchy two piece outfit, which gave the look of a classic black dress.
The top half featured shoulder pads and the eye-wateringly deep neckline, with bottom a simple black skirt.
The brunette beauty completed her killer look with some black sandle heels, chic red lipstick and her classic bobbed waves.
Co-star and heart throb Jon Hamm went opted for a monochrome suit with a classic white shirt and black brogue shoes.
Natalie has been in the acting business since childhood, but her career's showing no signs of slowing down.
The actress is set to make a triumphant return to the Marvel Cinematic Universe - a series of connected films based on Marvel Comics - as her character Jane Foster.
Jane was formerly the love interest of thunder god Thor, and Natalie will storm back onto our screens with Thor: Love and Thunder.
The director has confirmed that the film will see Natalie wield Thor's famous hammer, an honour reserved only for the worthy.
She's faced some drama recently in the form of musician Moby, who she denies she dated.
Moby, though, had different ideas, and wrote on Instagram : "I recently read a gossip piece wherein Natalie Portman said that we'd never dated.
"This confused me, as we did, in fact, date. And after briefly dating in 1999 we remained friends for years.
Natalie, speaking candidly to Harper's Bazaar , said: "I was surprised to hear that he characterised the very short time I knew him as dating because my recollection is a much older man being creepy with me when I had just graduated high school.
"He said I was 20. I definitely wasn't. I was a teenager. I had just turned 18."
