Jeff Bezos and Lauren Sanchez may ‘sneak off’ and get married

Jeff Bezos and Lauren Sanchez are so serious that they are planning on getting married, Page Six has learned.

The couple has been spotted around town wining, dining and watching Broadway shows.

But our source said: “It’s way more serious than date nights — I see them sneaking off to make things official.

“There won’t be a big ceremony. It will be something to mark their love and everything they’ve gone through to be together.”

In fact, Sanchez — who recently finalized her divorce from Hollywood power agent Patrick Whitesell — is in charge of refurbishing the Amazon chief’s new $80 million NYC home.

Bezos splashed out last month for three adjoining apartments at 212 Fifth Ave., overlooking Madison Square Park. Sanchez is believed to be using her regular interior designer Trip Haenisch, who designed the homes she shared with Whitesell.

To celebrate the Fourth of July holiday, Sanchez took her man for a ride in a helicopter she piloted herself, along with a co-pilot. The couple was spotted after landing on Manhattan’s West Side heliport in exclusive photos obtained by Page Six.

Jeff, dressed in jeans and a blue baseball cap, sat in the back by himself, and emerged looking relaxed after the flight.

But the two got out of the aircraft separately, with Lauren showing off her fit physique in a tight white top and flowing beige pants, before they jumped into an SUV and sped off.

The lovebirds are now believed to be splitting their time between New York and Seattle.

While Bezos’ divorce settlement from wife MacKenzie — with whom he shares four kids — was already announced, they chose this quiet holiday week to finalize the split in court.

MacKenzie is due to receive a 4 percent stake in Amazon, roughly equivalent to $38 billion, according to Bloomberg.

The cash injection will catapult her to ­become the world’s fourth-richest woman.

A judge in Bezos’ home state of Washington is poised to rubber-stamp the agreement this week, while the moving of shares to MacKenzie will be confirmed by Amazon in a regulatory filing.

Peter Walzer, president of the American Academy of Matrimonial Lawyers, said it was the “Godzilla of all divorces.”

MacKenzie has promised to give away more than half of her fortune, signing on to the Giving Pledge, a philanthropic campaign launched in 2010 by Bill and Melinda Gates and Warren Buffett.

She wrote in her pledge, “I have a disproportionate amount of money to share.”
