Jennifer Lawrence put on a typically chic display on Sunday evening, when she stepped out in head-turning style ahead of presenting an award onstage at the annual BAFTAs.
The Oscar-winning actress, 27, wowed as she made her way to London's Royal Albert Hall in a breathtaking black gown - in support of the Time's up movement - which featured an angular neckline with white chiffon straps.
She was joined at the ceremony by fellow Hollywood screen stars Angelina Jolie, 42, and Margot Robbie, 27, who exuded old Hollywood glamour in black gowns as they joined the protest in memorable style
Angelina and Jennifer's choice of wearing black gowns saw them standing in solidarity with the Time's Up movement, which has been a dominant theme at Hollywood awards shows this season.
Mother-of-six Angelina amped up the glamour, adding glittering Graff chandelier earrings - featuring 32.98 carats of diamonds - to her custom Ralph & Russo ensemble, which included a matching velvet wrap and vertiginous black heels.
With her raven tresses swept back in a sleek bun, she highlighted her natural beauty with a flattering palette of makeup that included a nude pink lipstick and smokey eye-shadow.
Angelina looked thrilled to be joined by her long-term friend as they soaked up the glamorous atmosphere together, hugging and joking while they made their way into the star-studded venue.
Loung Ung, who she has known for 16 years, complemented Angelina and showed her support for the worthwhile initiative by wearing a black full-length gown which featured sheer panelling.
Loung wrote the book First They Killed My Father, which Angelina adapted into her directorial passion, which told the story of a young girl's version of the 1975 Cambodian genocide from the child's five-year-old eyes until she turns nine.
Deadline previously reported that when Angelina was in Cambodia while in her 20s, she purchased Loung Ung's book from a street corner and became fascinated by the story.
She said: 'I didn’t realize how much my education was lacking and how much I needed to learn. This book was an education for me — about refugees and what children go through in a war. I wanted to find Loung.'
Angelina revealed that Loung went to Cambodia with her to adopt her eldest son Maddox, 16, and reflected on how she wanted to find the author after reading her book.
She shared: 'It was an education about refugees and what children go through in a war. I wanted to find her.'
'We clicked right away,' Loung added. 'She was really, really authentic. She hates it when I gush about her in public, but she’s a really cool person.'
First They Killed My Father faces off stiff competition in the Best Foreign Language Film against Elle, The Handmaiden, Loveless and The Salesman.
Accessorising her outfit with dangling emerald earrings, blonde beauty Jennifer opted to wear her golden locks down in a bone-straight style with a centre-parting, while siren red lipstick added a flourish of colour of her look.
The actress and philanthropist proudly displayed the dramatic train on her gown as she posed on the red carpet for the large gathering of photographers gathered at the hot-ticket event.
Margot also made a stylish arrival, hitting the red carpet in a floor-length, sleeveless Givenchy gown, which boasted a high neckline and semi-sheer overlay, descending into an intricately embroidered skirt.
With her blonde hair resting about her shoulders in gentle waves, she accessorised with dazzling earrings, while she toted a small, embellished black clutch bag.
As part of their participation in the Time's Up protest, the stars entered the imposing venue with movement activists by the side, further highlighting their dedication to the cause.
Also present on the night was Rochelle Humes, 28, who showed off her sleek figure in an extreme plunging black Suzanne Neville gown as she hit the red carpet ahead of presenting for EE.
Proudly displaying her natural curls, she added a dash of colour with oversized turquoise cocktail rings as she posed with one hand on her hip.
The event is being held at the Royal Albert Hall in for the second year in a row, after the move from the Royal Opera House.
Rochelle wore black in support of the Time's Up movement, which raises awareness of sexual assault, harassment and inequality in the workplace and helps sexual assault survivors take legal action against their abusers.
She said: ‘Being a woman, even before I had children, I had young cousins and things, I think it’s an important thing to do, and especially now I’ve got children too.
‘It’s a powerful message, it’s a strong thing to do, obviously it’s a night to celebrate everyone’s work, but fashion will always be what makes headlines the next day, that’s what makes these things work.
'Showing your support in that way, using that as a platform, using that to get the message across, is a positive thing, everyone is united in doing it together, it's powerful.'
