Jeff Bezos, 58, who founded online retailer Amazon in 1994, spent up to an hour admiring prized possessions with his family during a tour of the Queen’s main residence in London. Mr Bezos, who is worth an estimated £123billion, managed to see an exhibit which included Her Majesty’s signature diamond tiara.
The tiara is even set with 1,333 precious jewels and 169 freshwater pearls.
Bezos, who also founded aerospace manufacturer Blue Origin in 2000, spent £90 per ticket to visit Buckingham Palace.
According to the Sun, Mr Bezos has also met Top Gun star Tom Cruise.

A source told The Sun: “Bezos’ visit is already jokingly dubbed a ‘shopping spree’ by palace staff.
“He showed particular interest in the throne room and the ballroom.”
