Amazon CEO Jeff Bezos and his wife, MacKenzie, are set to divorce after a 25-year marriage.

The pair announced the move in a joint statement on Twitter.

“After a long period of loving exploration and trial separation, we have decided to divorce and continue our shared lives as friends,” the couple said in the statement.

Amazon, formed 25 years ago, this week eclipsed Microsoft to become the world’s most valuable listed company.

Mr Bezos (54) who founded Amazon, is the world’s wealthiest man according to the Bloomberg Billionaire Index, with an estimated wealth of $137 billion, some $45 billion ahead of Bill Gates.

The 48-year-old MacKenzie Bezos is a novelist, the author of The Testing of Luther Albright (2005) and Traps (2013).

The couple have four children – three sons, and an adopted daughter.

They got engaged after three months of dating and married shortly after, in 1993.

One year later he founded Amazon – which began as an online book retailer.

The company has since expanded into an e-commerce giant.

Amazon was worth $797bn (£634bn) when the US stock market closed on Monday, after rising 3.4 percent and moving past Microsoft, valued at $789bn.
