Lauren Sánchez Stuns in Racy Red Corset Dress with Jeff Bezos at White House State Dinner

The couple joined the Bidens and other luminaries in welcoming Japan's prime minister

Lauren Sánchez had everyone at the White House seeing red!

The journalist and philanthropist, 54, wore a revealing crimson corset dress to the White House state dinner on Wednesday, April 10. She and fiancé Jeff Bezos, 60, were among the many luminaries invited to the black-tie event honoring Japan's Prime Minister Fumio Kishida and his wife, Yuko.

Sánchez's off-the-shoulder gown featured intricate lace detail, corset-like boning and a floor-length skirt. She complemented the look with metallic open-toe heels.

Her dress was by far the most racy look of the dinner, which is typically a very formal, buttoned-up affair. President Biden and Dr. Jill Biden served as hosts.

Other media and entertainment attendees included Apple CEO Tim Cook and VP Lisa Jackson and actor Robert De Niro and his girlfriend Tiffany Chen. Japanese American Olympic medalists Kristi Yamaguchi and Alex and Maia Shibutani were also guests.

According to CBS News, the theme for the event was "a celebration of spring." Guests dined on an East-West menu that included shiso leaf fritters as a starter and dry-aged rib-eye steak with blistered shishito pepper butter, fava beans, morels and cipollini for the main course. Dessert included salted caramel pistachio cake, a matcha ganache, and ice cream.

Sánchez and Bezos recently returned from a trip to Japan, where their blended family explored temples, tried traditional painting and strolled among cherry blossom trees, which are currently in bloom.

"Japan, you’ve stolen our hearts 🌸," she captioned photos from the trip on her Instagram account. "Thank you, Japan, for the memories, the most beautiful sunrises, and those inside jokes 🌀🤍 〰️that’ll stick with us forever. We’re already dreaming of coming back."

According to Google Arts and Culture, red symbolizes good luck and happiness in Japanese culture.

It's also one of Sánchez's go-to colors; she wore a plunging red Lever Couture gown to the 2024 Vanity Fair Oscar Party last month. On the eve of her 54th birthday last December, Sánchez donned a sexy, red, lingerie-inspired look to celebrate with a group of girlfriends -- all of whom also wore red.
