Alexa Dell

Money was never an issue to Alexa Dell, the heiress of the Dell Technologies fortune (which is said to be worth a whopping $23.5 billion). A few years after dating Sean Rad, the CEO of Tinder, Dell got engaged to the real estate developer Harrison Refoua, who spent a reported $3 million to get her the perfect present.

While Dell dated Mr. Tinder himself, she met Refoua on a blind date set up by friends, not by a computer algorithm… Proving that old-fashioned dating still works, Dell and Refoua have been living happily together for four years now. The ring is an impressive 12-carat sparkler.
