Mary-Kate Olsen is now engaged to be married to boyfriend, French banker, Olivier Sarkozy.

Sarkozy, 44 and Mary-Kate, 27, have been dating for two years and already live together in their $6.25 million dollar townhouse in New York City.

Olivier Sarkozy is the half-brother of former French president Nicolas Sarkozy. The twin mogul and her banker beau met back in 2012 and have been going strong ever since. Sarkozy is a father of two, Julien, 12, and Margo, 10.

"Mary-Kate has made him a better father," a source told Us Magazine. "She remembers all the kids special events ... She thinks he's a great dad."

Just as the Full House twin has been accepted into Olivier's family, so has he into hers.

"Mary-Kate's family thinks Olivier is the best thing to happen to her," an insider tells the magazine. "They love him." 

The age difference seems to be yet another similarity between sisters Mary-Kate and Ashley, as Ashley is dating a man 20 years her senior. 

Congratulations to Mary-Kate, and may they enjoy a long lasting and extremely rich life together (can you imagine that bank account). Passport to Paris was one of my favorite Mary-Kate and Ashley movies; I just knew at least one of them would end up with a French man.

We also wish twin sister Ashley a happy fate with Moneyball director Bennett Miller.

These gals, they're just beyond us; so chic, so mysterious, such dedication to hold their cheeks in as much as they possibly can. It's all part of being a Fashionista, we get it, no shade. Their latest fashion line, Elizabeth and James, is doing just great. Glad to see that everything is going so well for the famous twins.

Do you think Mary-Kate and Olivier will have an extravagant fashionable wedding in Paris, France? Ooo la la!
