The billionaire CEO of Amazon, Jeff Bezos, has announced that he and his wife, MacKenzie, are divorcing. The world’s richest man revealed the split in a statement issued via Twitter on Wednesday morning, saying the two had decided to divorce after a trial separation. “We want to make people aware of a development in our lives. As our family and close friends know, after a long period of loving exploration and trial separation, we have decided to divorce and continue our shared lives as friends,” the statement says. “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.” Bezos met then-MacKenzie Tuttle, a novelist, in 1992 and they married a year later. They have four children together.
