Finally – some good news for Mary-Kate Olsen!

The 33-year-old’s plea for an emergency divorce from Olivier Sarkozy, her husband of five years, was originally rejected by judges, as they deemed it “unessential”.

(Despite it feeling very essential to her, as her soon-to-be ex-husband was in the process of kicking her out of their shared New York apartment and throwing all of her belongings away.)

However, the actress-turned-fashion-designer has refiled for divorce now that the courts in New York have officially reopened. Or more accurately, now that the courts are allowing divorces and lawsuits to be filed online.

But it might not be smooth sailing for Mary-Kate, as insiders reportedly claim that Olivier Sarkozy is not to be messed with. Especially if his divorce from first wife Charlotte Bernard is anything to go by…

“He sees himself as the alpha male. He will get even more French as he fights her,” an insider told Page Six.

“They can turn cold very fast on their wives once the relationship is over.

“Olivier seems like a fun guy when you meet him but he is a shark. Very tough…He’s not somebody you want to go up against.

“His divorce from his first wife got very messy for a while and they really went after each other. Don’t underestimate him if it gets messy with Mary-Kate.”

He may be tough, but we think that Mary-Kate just might be tougher. According to a source (via US Weekly), she insisted on “an iron-clad prenup” before tying the knot with the 51-year-old banker…

“Her business interests and fortune are protected,” the source continued, adding that she and twin sister Ashley Olsen have an estimated net worth of $500 million.

Good luck Mary-Kate… we’re all rooting for you!
