‘War’ Star Sienna Miller Dazzles Beside Oli Green at 2026 LACMA Gala
The annual Los Angeles County Museum of Art’s Art+Film Gala has long stood as one of the most prestigious intersections of contemporary fashion, cinema, and fine arts in Hollywood. Every autumn, leading luminaries gather beneath the glowing streetlamps of Chris Burden’s iconic Urban Light sculpture to raise vital funds for the museum’s curatorial initiatives and film education programs. The 15th annual celebration was no exception, delivering an unforgettable showcase that placed prominent artists and silver screen icons like Sienna Miller at the center of the cultural conversation.
This year’s gala paid tribute to two visionary storytellers whose creative contributions continue to redefine their respective fields: acclaimed Canadian director Denis Villeneuve and renowned Latvian-American artist Vija Celmins. Presented with longtime support from Italian luxury house Gucci, the formal affair was once again co-chaired by actor Leonardo DiCaprio and trustee Eva Chow, featuring a standout musical set by global pop superstar Rosé. With awards season fast approaching, the gathering offered an early glimpse at Hollywood’s most impeccably styled tastemakers.
Among the standout arrivals commanding the spotlight, Sienna Miller and her partner Oli Green coupled up for an effortlessly glamorous night out at the 2026 LACMA Art+Film Gala. The couple drew immediate attention on the red carpet, where their coordinated presence was captured in widely circulated footage shared across social media by videographer jpasc24. Posing together against the venue’s iconic illuminated columns, the duo demonstrated an undeniable chemistry that quickly captured the imagination of onlookers and online admirers alike.
Miller turned heads in a luminous silver minidress from Gucci, crafted from shimmering metallic chainmail that caught every flash of the evening’s cameras. The sleeveless silhouette featured a graceful, draped halter neckline paired with a straight hem, creating a balanced blend of retro opulence and modern sophistication. Completing the look with a sleek black clutch and understated accessories, the actress let the striking dress take center stage, while Green complemented her aesthetic in a classic, tailored dark suit accompanied by a crisp white shirt and a slender black tie.
The glamorous red carpet outing marks yet another stylish chapter for the high-profile couple, who first went public with their romance in early 2022 before expanding their family together two years later. Whether turning heads during Paris Fashion Week or stepping out in custom tailoring at Wimbledon, the engaged pair has developed a reputation for understated elegance at major public gatherings. Their coordinated appearance in Los Angeles served as a testament to their enduring sartorial synergy, effortlessly commanding the attention of fashion critics and attendees.
Miller’s radiant presence at the museum gala coincides with one of the most creatively ambitious periods of her screen career. The British actress recently earned glowing notices for her leading role opposite Dominic West in creator George Kay’s high-stakes legal thriller ‘War’, which debuted on HBO and Sky. Portraying international film icon Carla Duval embroiled in an explosive, multi-million-pound divorce, Miller delivered a performance anchored in biting wit, magnetic charm, and undeniable gravitas.
The intense courtroom drama proved an immediate success with audiences and critics alike, with television journalist Lucy Mangan praising the show’s relentless momentum in her review for The Guardian while celebrating its darkly comic, high-society warfare. The series followed Miller’s standout contribution to Kevin Costner’s sweeping frontier western ‘Horizon: An American Saga – Chapter 1’, demonstrating her ability to transition seamlessly between sprawling period epics and modern psychological power plays. Both projects have reaffirmed her standing as one of the most versatile and captivating performers working in the industry today.
As the entertainment calendar gears up for the forthcoming awards campaign, the LACMA Art+Film Gala proved once again that high culture and Hollywood royalty make an unbeatable combination. Between honoring master filmmakers and providing a platform for exquisite couture, the evening reminded fans why it remains a marquee fixture of the season. With Miller and Green anchoring the night’s fashion highlights, the event delivered an evening as timeless as it was dazzling.
