MacKenzie Bezos and Jeff Bezos are no longer married, but she made so much money out of their divorce settlement that she may as well still be married to his cash. She walked away with $35bn in what's believed to be the largest divorce settlement ever.
She was by her husband's side as he grew Amazon from a tiny website into a globally dominant brand - they married in 1993, and stayed together until early 2019. As she supported him for so long, she's entitled to her share of the spoils.
