Lauren Sánchez was all smiles on one of her final date nights as a fiancée.

The bride-to-be rocked a vintage Alexander McQueen dress while stepping out with Jeff Bezos for a pre-wedding dinner in Venice, Italy, on Thursday.

The one-shoulder ensemble featured stripes of white sequins.

Sánchez, 55, wore her hair down in waves for the outing and carried a black clutch.

As for Bezos, the 61-year-old sported a black suit, a cream T-shirt and sunglasses.

The couple, who went public with their romance in 2019 and got engaged four years later, grinned and waved at onlookers.

They did the same while arriving in Venice via helicopter and being helped into a water taxi on Wednesday.

Sánchez stunned in a sleeveless black gown and stilettos.

A slew of A-listers have also been photographed flocking to the floating city this week for the couple’s upcoming nuptials.

Ivanka Trump and her family members arrived on Wednesday, followed by Oprah Winfrey, Kim Kardashian and Orlando Bloom the following day.

We hear that wedding guests have been kept in the dark about the wedding festivities’ locations — but were provided with mood boards for outfit inspo.

“The guests don’t know the locations,” a source recently told Page Six. “They were given times and no details. They just get taken there.”

Sánchez and Bezos are staying secretive as part of their plan to outwit rampant protesters.

“The couple has deliberately kept multiple options open, booking several venues across a range of dates,” a Venetian insider told us.

“The strategy serves both to mislead paparazzi and protesters, and to ensure contingency plans in the event of last-minute logistical setbacks.”

However, we hear the pair are expected to hold a welcome ceremony at the beachside restaurant La Pagoda.

The nuptials will reportedly take place at Teatro Verde on the island of  San Giorgio Maggiore.

Sánchez and Bezos have each been married before to Patrick Whitesell and MacKenzie Scott, respectively.
