Alexa, what was he thinking?

So-called tech genius Jeff Bezos sent a series of sleazy photos, X-rated selfies and explicit texts across the internet — all behind wife MacKenzie’s back!

In a stunning new revelation as part of the The National ENQUIRER’s blockbuster exposé, we can reveal the Amazon founder — worth an eye-watering $144 billion — was so smitten with his mistress, Lauren Sanchez, the wife of powerful Hollywood talent agent Patrick Whitesell, that he literally lost his pants!

A cache of lewd selfies taken by Bezos and seen by reporters from The ENQUIRER are so shocking we dare not print them — but their existence could devastate his standing in the upper ranks of the tech world.

Several of the pictures show the billionaire posing with his shirt off in front of the mirror, and in another, he grins with just a towel wrapped around his waist in a steamy bathroom.

What’s more, the horndog e-commerce mogul even sent Sanchez a below-the-belt selfie — otherwise colloquially known as a “d*ck pic” — in an unsparing close-up that’s too explicit to describe in detail.

Indeed, The Enquirer’s editors decided not to publish the image or details about it out of respect to the billionaire’s privacy.

However, the relevance of the photograph and the sexually charged text messages has become ever more relevant given his insistence that the relationship did not begin until after he separated from his wife.

Bezos’ decision to share the intimate images over a span of months is a stunning lapse of judgement from the man who oversees one of the largest tech companies in the world.

It also provides a window into his mind — obsessed with his own appearance, and naively overlooking the possibility that the images could be leaked and published.

While Bezos and Sanchez insist their relationship began “in the fall” only after they had ended their marriages, The ENQUIRER can reveal the raunchy photos and texts were sent many months earlier!

In one message sent on June 1, 2018, and obtained by The ENQUIRER, on newsstands today, Bezos sent Sanchez a shirtless photo and told her:

“You know what I want? I want to get a little drunk with you tonight. Not falling down. Just a little drunk. I want to talk to you and plan with you. Listen and laugh … I basically WANT TO BE WITH YOU!!! Then I want to fall asleep with you and wake up tomorrow and read the paper with you and have coffee with you.”

Bezos — who owns The Washington Post — was at pains to point out through a lawyer that he “supports journalistic efforts and does not intend to discourage reporting about him.”
