It's official! Mary-Kate Olsen and French banker Olivier Sarkozy are engaged! The odd couple confirmed their happy news to Us Weekly earlier today.

The 27-year-old twin and her 44-year-old paramour, who is the half-brother of former French president Nicolas Sarkozy, first began dating in 2012. The duo live together in a $6.25 million townhouse in New York City.

Despite the age difference, the twosome have been a fixture on the New York scene. This will be Olsen's first marriage and Sarkozy's second. The distinguished gentleman previously married to Charlotte Bernard, whom he had two children, Julien, 12, and Margo, 10.

Interestingly, a love of older men seem to be a family trait. The child star-turned-fashion designer's twin sister, Ashley, has been linked to Moneyball director Bennett Miller, who is 20 years her senior.
