On Wednesday, the world's wealthiest couple announced that they were getting a divorce, proving once and for all that money really can't buy happiness. Amazon founder and tech tycoon Jeff Bezos posted a joint statement with his wife of 25 years, MacKenzie, on Twitter to share with the public that "after a long period of loving exploration and trial separation, [they] have decided to divorce and continue [their] shared lives as friends."

Now, despite rumors of a pretty gruesome affair involving Jeff and his friend's wife, the estranged Mrs. Bezos is sure to come out on top. If she receives even one-third of her husband's wealth, MacKenzie will become the richest woman in the world, surpassing the likes of L'Oréal heiress Francoise Bettencourt Meyers and Walmart heiress Alice Walton. 

And although she's spent the last two decades supporting her husband's rise to the top, MacKenzie Bezos has cultivated success in her own right while staying mostly out of the spotlight. Click through for everything you never knew about the woman behind the mogul.
