Plagued by the looming threat of disruptive protests, the upcoming Venetian wedding of Amazon founder Jeff Bezos and former news anchor and licensed pilot Lauren Sanchez — which is expected to be a lavish, multimillion-dollar affair — may be one of the most anticipated and closely guarded events to be held in the floating city of love.

Spokespeople for the couple remain tight-lipped and invited guests have been required to sign NDAs, but a lid cannot be kept on widespread speculation about every detail of the event that is expected to take place this week.

At Harry’s Bar, a fabled institution that once counted Ernest Hemingway among its customers, the waiters are hoping some of the 200 guests — a mix of A-list celebrities, political dignitaries and powerful business executives — might stop in for one of their famous Bellini cocktails. Whether or not Bezos will bring his yet-unnamed groomsmen there, as George Clooney did when he married Amal Alamuddin in 2014, is anyone’s guess. “We hope so,” one of the waiters told CNN. “We can’t divulge anyone who has made a reservation. We protect the privacy of all of our guests, not just the billionaires.”

From the date to the guest list, possible venues and the bridal gown, the rumor mill is spinning at a rapid pace.

Proceedings are being overseen by boutique event planners Lanza and Baucina, the Italian duo who transformed Venice’s Grand Canal into a red carpet for the Clooneys’ glitzy wedding.
