Mary-Kate Olsen, one-half of the adorable Olsen twins known for their shared role on the hit show Full House, is engaged to her much older boyfriend Olivier Sarkozy. Mary-Kate is 27 and Sarkozy is 44 years old. Their age difference has been a hot topic of conversation since they started dating.

The engagement shouldn’t come as a complete surprise since the two were spotted checking out some very expensive Neil Lane engagement ring designs recently.

Olivier Sarkozy is the half-brother of the former French president Nicolas Sarkozy. He is a well known French banker. He has lived together with Mary-Kate Olsen in a $6.25 million townhouse in New York’s Lower East Side for at least a year. This will be the first marriage for the Olsen twin (will twin sister Ashley Olsen be her maid of honor when she ties the knot?) and the second for Sarkozy. He has two children with his ex-wife Charlotte Bernard, from whom he was divorced back in 2011.

Younger Olsen sister Elizabeth Olsen talked with Andy Cohen recently and said Mary-Kate was on a romantic vacation the week of Mary-Kate’s 27th birthday in February. Cohen asked Elizabeth which of the Olsen twins was her favorite.

“Ashley,” she answered, quickly explaining with a laugh that Mary-Kate forgot her birthday while on vacation with Sarkozy.

“But I don’t hold grudges against Mary-Kate forgetting mine. She was out of town,” Elizabeth was quick to add.

No word has escaped yet as to when Mary-Kate Olsen and Olivier Sarkozy will take that walk down the aisle, but it will definitely be fun to learn of any wedding plans as they are shared with the media. Since Mary-Kate and Ashley Olsen are successful–albeit a bit odd–fashion designers, it will be interesting to see if the twins design Mary-Kate’s wedding gown, or if she chooses one created by a fellow designer.

Can you believe little Mary-Kate Olsen who played the positively adorable Michelle Tanner on Full House back in the 1980s and 1990s is even old enough to get married? And now she’s engaged to a man 17 years her senior.
