Lauren Sánchez made an official appearance at the 78th Annual Cannes Film Festival on Monday, attending the Global Gift Gala, where she was honored with the Global Gift Women Empowerment Aware for her advocacy through the Bezos Earth Fund and This Is About Humanity. The children’s book author and fiancée of Amazon founder Jeff Bezos posed on the white carpet alongside Eva Longoria in a sleek, strapless gown fit for the festival’s black-tie standard.

Sánchez wore a form-fitting black gown featuring a structured bodice with a sweetheart neckline. The design was embellished with intricate sequin detailing, while the skirt fanned into a soft, cascading silhouette with a dripping effect at the hips. Her shoes, which barely peeked out from her train, featured a sharp box toe.

She kept accessories classic, opting for a diamond-encrusted choker featuring a square-cut center stone and matching oversized diamond stud earrings. For glam, Sánchez styled her hair in an updo, with a soft side-parted bang framing her face. Her beauty look included a diffused smoky eye and a glossy pink lip for a polished finish.

Earlier in the festival, Sánchez found herself at the center of an amusing case of mistaken identity. A lookalike couple, complete with dark sunglasses, a bow tie, and a strapless gown, drew attention from festivalgoers who mistook them for the Blue Origin executive and the Amazon founder at the “Dossier 137 (Case 137)” premiere.

Sánchez has leaned into classic Hollywood glamour in recent appearances. In April, she attended the 2025 Breakthrough Prize ceremony in a vintage 1994 John Galliano gown once worn by Sophia Loren. “I wore a little piece of history,” she shared on Instagram. “This 1994 John Galliano dress was once worn by the legendary Sophia Loren — an icon of strength and timeless beauty.”

Co-chaired by Eva Longoria and María Bravo, the 12th annual Global Gift Gala featured performances by Laura Pausini and the Gipsy Reyes Heritage, and included a live auction to benefit charitable initiatives such as Casa Ángeles in Marbella, Spain, and an orphanage in Vietnam.

The 2025 Cannes Film Festival concludes on May 24. Films premiering at this year’s festival include Wes Anderson’s “The Phoenician Scheme,” Julia Ducournau’s “Alpha” and Lynne Ramsay’s “Die, My Love.”
