Despite a 17-year age difference and the fact that they'd only been dating for less than two years, Mary-Kate Olsen and Olivier Sarkozy got engaged earlier this year.
Now it seems the unlikely couple is continuing to move quickly as they reportedly got married in a small, secret ceremony some time over the summer.
Mary-Kate and Olivier were spotted having lunch in the Hamptons recently, and witnesses say they were both rocking wedding bands.
The change in MK's bling would've been particularly easy to spot, as she had previously been wearing an $81,000 antique engagement ring that featured a giant rock.
Mary-Kate has reportedly now switched the ring out for an understated band, and various media outlets are reporting that she and Sarkozy have indeed made it official.
Sarkozy - the half-brother of former French president Nicolas Sarkozy - is the latest in a long line of high-profile, very well off men with whom Mary-Kate has been romantically involved.
She broke up with Nate Lowman - a celebrated NYC artist - just months before getting involved with Sarkozy.
Of course, just because her other half has settled down, don't expect Ashley Olsen to walk down the aisle any time soon. Last we saw her, Ashley was having one night stands with Johnny Depp and very much enjoying the single life.
Anyway, congrats to Mary-Kate and Olivier! May you enjoy a life of love, happiness, and obscene wealth!
