Jeff Bezos has candlelit dinner with Lauren Sanchez in Kips Bay

Amazon billionaire Jeff Bezos and girlfriend Lauren Sanchez continue to quietly carry on their relationship.

The couple were spotted at Japanese restaurant O Ya in Kips Bay on Thursday, where, a spy told us, “they were having a candlelit dinner.”

The couple were spotted “sipping cocktails and eating sushi.”

Bezos and Sanchez have mostly kept a low profile since their scandalous relationship came to light — but she was spotted outside the building where he bought a massive penthouse and two adjacent apartments overlooking Madison Square Park for $80 million earlier this month.

They were also recently seen cavorting in Key West, Fla., and Sanchez dined solo at NYC’s see-and-be-seen spot Nello in May.

They’d been spending time apart after the news of their secret relationship broke in January — and Bezos’ team launched an investigation into how the couple’s racy texts were leaked to the National ­Enquirer.

Either way, in May a source told Page Six that Sanchez had been “putting a lot of pressure on Bezos for them to be seen in public,” and “they’re now free to live their lives together.” And have sushi by candlelight.

Their divorces from their exes have both been finalized.
