Exclusive! Inside Lauren Sánchez and Jeff Bezos’s Beverly Hills Engagement Party

On the eve of her Vogue debut, Lauren Sánchez and her fiancé, Jeff Bezos, were fêted with an engagement party. And like all things the couple does, the event was not to be ignored. The venue? Barry Diller and Diane von Furstenberg’s Beverly Hills home. Diller and von Furstenberg, as two of the couple’s closet friends, played host, welcoming Oprah Winfrey, Salma Hayek Pinault, Barbra Streisand, Kris Jenner, Sarah Staudinger, Robert Pattinson, Suki Waterhouse, Miranda Kerr, and more to the engagement party.

Sánchez wore an off-the-shoulder Laura Basci mini dress with a basque waistline and a custom-made layered Lorraine Schwartz cross necklace. Bezos wore a light-colored blazer over a T-shirt. Basci, a Swiss designer who most recently dressed Gwyneth Paltrow at the CFDA Awards, has an atelier in Los Angeles. Upon seeing the dress, Sánchez knew it was the one.

At dinner, where long tables were set with meadowy arrangements of dahlias, Winfrey proffered her signature affection, embracing the bride-to-be. Kris Jenner, dressed in Chanel, posed for pictures with Staud designer Sarah Staudinger. All were treated to a speech from Bezos, which was dedicated to his fiancée, and a performance from Jewel.

“They’re very in love with each other—they’re demonstrably in love,” Diller told Vogue. “She’s lit him up in the nicest ways. She’s a great stimulant.”

Followers of the couple’s matrimonial timeline might recall an earlier engagement party held this summer on Bezos’s yacht, Koru, with attendees Leonardo DiCaprio, Bill Gates, and Queen Rania of Jordan. With one event held at sea, and the other held on land, the setting for their actual wedding is anyone’s guess. Our bet’s on outer space.
