Things you don't know about Mary-Kate Olsen's odd marriage

Mary-Kate Olsen's showbiz career hit the ground running so soon after birth that it's shocking to consider she's only been among us since 1986. In the space between, the pint-sized superstar has gone from being a precocious youngster whose brand was inseparable from twin sister Ashley Olsen, to an international businesswoman and model, though not without some slightly precarious bumps in the road along the way. We're relieved to report that Mary-Kate has now settled down into the quiet rhythms of a married life with billionaire Olivier Sarkozy, though theirs is a rather peculiar union. Nothing bad—just odd. Let's take a look at some of the strange facts about Mary-Kate and her man.

Her boo is the step-brother of France's former President

Well, that's an impressive familial connection. Imagine if Justin Bieber started dating a cousin of Barack Obama…or something. Olivier's half-brother, born from a first wife, is Nicolas Sarkozy, a name foreign-affairs challenged Americans may vaguely recognize. He served as president of France from 2007 to 2012, ruling during the worst years of the recent world economic crisis. Step-brother Olivier is a prominent investment banker. If nothing else, that combo should make for some vibrant dinner conversation between stale jokes about John Stamos' hair.

His ex-wife despises her

Following in his father's footsteps, Olivier's wedding to Mary-Kate was his second go-around at marriage. His first wife, Charlotte Sarkozy, most definitely does not approve, particularly in regard to the newlywed's age difference (Olivier was 42; Mary-Kate was 25 when they reportedly started dating). "That's not right. It's grotesque," Charlotte told the National Enquirer. Those are strong words; maybe even unfair, but Charlotte, is coming from the perspective of a mother and children's book author who supposedly doesn't want stepmom Mary-Kate—a woman with a hard-partying reputation—hanging around her kids. This Thanksgiving table just gets tenser and tenser.

They dated for three years and shared a $13.5 million home

The marriage between Mary-Kate and Olivier was no spur-of-the-moment thing. Rumor has it, Olivier was revved up and ready to race down the aisle after just ten months of dating, but Mary-Kate made him slow his roll. They dated for three years, taking up residence together in a $13.5 million townhouse in Manhattan before tying the knot. The insane domicile includes a hall of mirrors, a rooftop swimming pool, a massive garage, an artist's studio, a working elevator, and a private garden with fountain. So, um, nice starter home.

Some distasteful PDA

Look, we get it, mi amores. Love still young in bloom is like a little shot of madness to a couple, encouraging them to forget where they are and cuddle up close anywhere and everywhere. Little kisses, locked hands, doting pats. Okay, cut it out. That ish is gross. And it's easy to make fun of. Knock it off, you guys!

The French media can't get enough of it

French blogs and magazines just can't get enough of this little May-December (or mars-décembre) romance, at the expense of the elder husband, of course. Calling him "the little French lover" and other diminutive nicknames, the foreign press seems determined to lampshade creepiness and expose a trend for dating younger woman that seems to have a long and fruitful history in the Sarkozy family tree.

Plus, there's the whole half-brother President thing. That kind of attention tends to suck all sorts of dirty laundry into the public eye. Still, we can't say we feel all that bad for Mr. Mary-Kate Olsen, with all that money and, naturally, his new true love.

Their wedding was low-key and smoky

When the couple finally tied the knot, they didn't make it an ostentatious affair. Details are sparse, but word is the couple reportedly kept it relatively low-key, by celebrity standards, with some 50 guests commiserating in a lavish Manhattan apartment with bowls and bowls of cigarettes topping every table. The most egregious omission? No one invited Bob Saget. Poor Dad, his once-full house so empty.

They fly under the radar

Mary-Kate and sister Ashley used to be everywhere and constantly hounded by paparazzi, but now that she's an honest woman, Mary-Kate and Sarkozy have skirted the spotlight. In fact, they keep such a low profile that not even Mary-Kate's former Full House co-stars see her that often. After their November 2016 wedding, the newlyweds weren't seen out in public together for nearly two months.

A source told E! News that part of why you don't see Mary-Kate and Sarkozy around is because they're usually in the City of Light. "Mary-Kate has a fabulous life with Olivier and they spend a lot of time in Paris where they are both very happy," the insider said. "She has become immersed in his world."

They may have influenced Ashley's dating life

The huge age difference between Mary-Kate and Sarkozy is almost nothing compared with Ashley and her most recent beau. Perhaps in an effort to outdo her sister, Ashley has been linked to artist Richard Sachs since summer 2016, when she was 30 and he was 56. The couples have even been spotted on numerous double dates together.

One witness told Page Six that they spotted Ashley and the divorced Sachs canoodling. "It looked like she was dining with her grandpa, but they were holding hands and snuggling."

In November 2016, a source told the site, "Olivier is a longtime friend of Richard's. They have the same group of friends, so it's possible he may have introduced them… He's so private. They're certainly comfortable given the fact that they keep being seen out. It seems like it's more than just dating. They've been together for the past several weeks, so it's definitely a real relationship."

She feels like she has to be domestic

Though Mary-Kate has been working pretty much since birth and can certainly afford to hire some help around the house, she admitted to Net-A-Porter's The Edit in March 2017 that she does feel some pressure to be domestic too.

"I think we're lucky. [Working hard] comes quite naturally for us. We don't need so much time to sit and think and ponder," she said of her and Ashley's ambitions. "But then I have a husband, two stepkids and a life; I have to go home and cook dinner. I ride horses on the weekends. You find the thing that helps you relax, and if you don't have it, you have to look for it. Or you get burned out, and then you're not productive."
