The world’s richest person had an affair with the eighth-richest person’s wife last year at Art Basel, according to a bombshell new report from the Wall Street Journal. Tesla and SpaceX founder Elon Musk “engaged in a brief affair last fall with the wife of Sergey Brin, prompting the Google co-founder to file for divorce earlier this year and ending the tech billionaires’ long friendship, according to people familiar with the matter,” the Journal reported Sunday. A big-time big tech melodramatic mess, in other words.

The story alleges that Brin has since directed his financial advisers to sell off his investments in Musk’s companies. The Journal was unable to confirm any of the sales or how big they may be, but reports that during the 2008 financial crisis, Brin provided about $500,000 to the then-struggling Tesla.

In a January divorce filing citing “irreconcilable differences” with his wife of almost four years, Nicole Shanahan, Brin said they had been separated since December 15. The Journal’s sources said the alleged affair occurred when Musk and Shanahan were both at the swank Art Basel festival earlier that month in Miami, at which point Brin and Shanahan’s marriage was already in trouble for other reasons.
