It’s every stay-at home dad’s worst nightmare. A previously high-flying man puts his career on hold to allow his more successful wife to continue working, while he brings up their newborn child.

So far, so progressive: after all, what truly modern man wouldn’t do the same?

Then, a couple of years later, when your gurgling baby turns into a beautiful, walking, talking little person, mum suddenly files for divorce – and demands custody of the child you reared while she made her fortune.

It would be a bitter pill for any man to swallow – and right now, Romain Dauriac, aka Mr Scarlett Johansson, is publicly choking on it.

Two years ago, shortly after the couple married, Dauriac gave up his career as a magazine editor and manager of a creative agency to raise the couple’s daughter, Rose, in Dauriac’s native France.

Johansson split her life between France and Hollywood, and, enabled by her husband’s support on the domestic front, in 2016 alone her movies grossed $1.2 billion and she pocketed $25 million. That took her career gross to $3.3 billion, making her the tenth highest-grossing actor of all time.

That’s not bad for an actor who’s been a vocal critic of the gender pay gap in Hollywood, where she claims “sexism is real”. (As an aside, one wonders, will Johansson continue her quest for gender equality and give half her fortune to Dauriac, or at least half the dough she earned while he kept baby?)
