Lauren Sánchez waltzed into 1600 Penn. Ave with her fiancé Jeff Bezos in hand — but it was her racy corset dress that turned heads at Wednesday’s lavish state dinner.

The former journalist, 54, rocked a red gown that featured a plunging neckline adorned with lace.

The off-the-shoulder Rasario dress ($2,200) also featured corset-like boning and a floor-length silk skirt.

She completed her risqué ensemble with a pair of Gianvito Rossi Flavia mirrored leather pumps ($1,200).

Sánchez let her hair flow behind her ears, revealing her huge diamond earrings. She topped off her look with a sparkly clutch.

The philanthropist’s outfit was far riskier than what guests typically wear to a White House state dinner, where guests often opt for formal, buttoned-up outfits.

For his part, the billionaire Amazon founder and Washington Post owner opted for a black tuxedo paired with a silk bowtie atop a crisp white shirt.

Sánchez and Bezos, 60, rubbed elbows with a handful of famous faces and important figures.

The black-tie event honored Japan’s Prime Minister Fumio Kishida and his wife, Yuko as President Biden and Dr. Jill Biden served as hosts.

Legendary actor Robert De Niro and his girlfriend Tiffany Chen were also in attendance, as well as Apple CEO Tim Cook, VP Lisa Jackson, and Japanese American Olympic medalists Kristi Yamaguchi and Alex and Maia Shibutani.

Upon arrival, attendees were welcomed in the White House East Room, where more than 200 guests dined on house-cured salmon and dry-aged rib-eye steak.

JP Morgan Chase CEO Jamie Dimon and Treasury Secretary Janet Yellen, spotted with wine glass in hand ahead of Biden and Kishida giving introductory toasts, were also toward the center of the room.

“We both remember the choices that were made to forge a friendship,” Biden, 81, said during his toast. “We both remember the hard work, what it has done to find healing.”

“Tonight,” the president continued, “We pledge to keep going.”

Paul Simon, 82, provided the evening’s entertainment in the State Dining Room — beginning shortly after 10 p.m. with the songs “Graceland” and “Slip Slidin’ Away.”

The former Simon & Garfunkel singer is said to be a favorite of the First Lady’s.

Just days ago, Sánchez and Bezos returned from a trip to Japan where they enjoyed seeing the sights and spending quality time with their blended family.

In images shared on Instagram, Sánchez gave fans a sneak peek into their lavish trip, which included traditional painting, meditation, and several family gym workouts.

She also shared a snap of the cherry blossom trees that are in bloom.

“Japan, you’ve stolen our hearts 🌸,” she captioned the images. “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.”
