The man behind the surprise engagement of Hollywood star Scarlett Johansson is Romain Dauriac, who has been together with her for about 10 months.
Very little is known about the man, especially by modern standards.
News that Scarlett Johansson is engaged to Romain Dauriac led to a deluge of media coverage and Tweets from fans, many of whom asked, "who?"
The French journalist is quiet on social media, having not Tweeted from his account in three years. That's more than Scarlett, who doesn't even have one.
Clearly, this is the rare celebrity couple who values privacy.
