A different source said Bezos and Sanchez have been spotted spending more and more time together in recent months.
“Lauren and Jeff have been spending a lot of time together over the last yearand especially the past few months,” the source said. “At first it was socially at parties… here and there. But their time together has definitely seemed to evolve, raising some eyebrows. Jeff has met a small group of Lauren’s girlfriends, too. The two of them are sort of thick as thieves right now.”
Bezos and MacKenzie announced in a statement on the billionaire’s Twitter account that they had decided to continue their “shared lives as friends.”
“We feel incredibly lucky to have found each other and deeply grateful for every one of the years we have been married to each other. If we had known we would separate after 25 years, we would do it all again,” they added in the statement.
“We’ve had such a great life together as a married couple, and we also see wonderful futures ahead, as parents, friends, partners in ventures and projects, and as individuals pursuing ventures and adventures. Though the labels might be different, we remain a family, and we remain cherished friends,” they continued.
In 2018, Bezos bested Bill Gates on Forbes’ annual ranking of the world’s billionaires. Today,Bloomberg reportsthat Bezos’ net worth is now $137 billion, making him the richest person in the world.
