6 Who Is Rose Dorothy's Father?

The father of Scarlett Johansson's daughter Rose Dorothy is Romain Dauriac. He's a French journalist, and the two of them started dating in 2012. Their relationship moved fairly quickly. They were engaged within a year of dating, and in 2014 they welcomed their daughter Rose Dorothy Dauriac into the world, getting married just a month after. Unfortunately, they couldn't make it work. They didn't share a lot of details about their split, but it seems that they weren't really compatible. Reportedly, Romain wasn't on board with how much Scarlett had to work and travel, and Scarlett didn't want to be pinned down because, of course, acting is her life. So, ultimately, they had different expectations, and they decided to go their separate ways.

5 How Scarlett Johansson Handles Co-Parenting

Now that Scarlett is happily married to Colin Jost, all the personal issues she may or may not have had with Romain Dauriac are obviously behind her. But because they have a daughter together, they will forever be a part of each other's lives, so learning to get along was a necessity. The two of them had a tense custody battle, but eventually worked things out. Even then, though, co-parenting is not without its challenges, but they both want the best for Rose, so they make it work.

"You know, understanding what it is to co-parent—that’s a very specific thing. It’s hard to raise a child with someone you’re no longer with. It’s hard," she explained to Vanity Fair. "It’s not probably how it’s ‘supposed to be’—in quotes—or whatever…. But, you know, I think my ex and I do it as well as we can. You have to prioritize your child and not put yourself in the middle. It has its challenges."
