Amazon chief Jeff Bezos' affair with his friend Patrick Whitesell's wife Lauren Sanchez gets even MORE scandalous!

We all thought their respective spouses were blindsided by the National Enqirer report that outed the couple's affair but we're finding out that's NOT the case. Whitesell, a bigwig Hollywood agent, and MacKenzie, a novelist and social activist, already knew their spouses were hooking up, according to a new People magazine report.

It wasn't until the news went public that Jeff and MacKenzie announced their separation via Twitter but they'd been planning that statement: "Their families dealt with this in the fall," a source told the mag.

The source says the two struck up a relationship while working on several projects together and "gradually" developed romantic feelings for each other. But it was Bezos and Whitesell that were first friends and then dinners with spouses led to Jeff and Lauren striking up a relationship on their own. And seriously ... WHO DOES PROJECTS WITH THEIR FRIEND'S WIFE???!!!

Well MacKenzie's the one who'll be laughing all the way to the bank. The richest man in the world (said to be worth $137 BILLION) didn't have a pre-nup with his wife so she'll be 50% and PERHAPS controlling interest in Amazon. What will investors do? Well so far, Wall Street doesn't give a damn. If we all keep subscribing to Prime and buying our entire LIVES on Amazon.com, the e-commerce site should continue to thrive.
