Jeff Bezos and Lauren Sanchez party at swanky brunch

He may not be the world’s richest man today, but Jeff Bezos is still partying over the moon after sending himself and William Shatner to space — complete with boozy brunches, chair dancing and lunar-themed cocktails.

The Amazon founder was spotted at brunch at Le Bilboquet over the weekend with girlfriend Lauren Sanchez — and a few of her gal pals, along with security — when he was overheard ordering a drink called “Fly Me To The Moon.”

We’re told the cocktail, a take on the traditional “Aviator,” is made with rum, lemon juice and creme-de-violette.

Our spy told us that Bezos and his crew of ladies were having a blast, with Sanchez and pals getting up and dancing to the DJ.

While Bezos did not stand up to bust a move, a spy tells us “He was clapping in his chair and swaying.”

Bilboquet is known for its socialite-filled Saturday brunch party.

Sanchez, 51, and Bezos, 57, were also recently spotted at power dining spot the Grill for dinner, spies told Page Six. Sources said the couple was “whisked through the lobby” by security, with a restaurant hostess intent on clearing a path for the pair.

This month, they’ve also been spotted in town having lunch with Sanchez’s ex, Tony Gonzales, and his wife, October, and attending the three-hour play, “The Lehman Trilogy.”

Bezos just fell in the richest rankings to Elon Musk, 50, who was reinstalled at No. 1. The SpaceX mogul couldn’t resist taking a dig at the Blue Origin founder on Twitter, sending him an emoji of a second place medal.

Bezos’ space company just sent “Star Trek” star Shatner, 90, into space, with the actor calling it the “most profound experience I can imagine.” Bezos himself also went on a previous rocket trip.
