Honestly, it’s kinda wild how one of the biggest stars on the planet—someone who basically lived in a Marvel suit for a decade—manages to keep her home life feeling so... normal. Or as normal as it can be when your stepdad is on Saturday Night Live. When we talk about scarlett johansson children, we aren't talking about kids who are constantly shoved into the TikTok spotlight or walking red carpets in miniature tuxedos.
She's protective. Like, "don't even think about it" protective.
Scarlett has two kids, Rose and Cosmo. They’re nearly seven years apart, which means she’s basically lived through two entirely different eras of parenting. She has Rose Dorothy Dauriac, who is now 11 and navigating that middle-school-adjacent chaos, and little Cosmo Jost, a 4-year-old who apparently spent a good chunk of his toddlerhood being obsessed with his own feet. It’s a relatable mix of high-stakes privacy and typical "mom" complaints about back-to-school schedules being "rude."
The "Flower Power" Connection Most People Miss
You probably didn't notice this, but Scarlett actually has a theme going. She mentioned on The Kelly Clarkson Show a couple of years back that both her kids are named after flowers.
Rose is obvious. But Cosmo?
Most people hear "Cosmo" and think of the magazine or the Seinfeld character (Kramer, anyone?). But a Cosmo is actually a really pretty, bright flower—part of the sunflower family. Apparently, Rose was totally on board with the name because of that connection. It’s a sweet, subtle detail that most fans completely breeze past.
Rose Dorothy Dauriac: The 11-Year-Old "Boss"
Rose was born in 2014, right as the Avengers fever was hitting its peak. Her dad is Romain Dauriac, a French journalist and art dealer.
Scarlett and Romain split up back in 2017, and while the divorce got a bit messy in the headlines regarding custody and moves to France, they've since settled into a co-parenting groove. Scarlett has joked that Rose is "painfully girly" and a bit of a "boss."

In an interview during the 2025 press run for Jurassic World Rebirth, Scarlett admitted she’s finally starting to give Rose some "grown-up" advice. She even had to explain the concept of "ghosting" to her 10-year-old (at the time) after a boy at school liked Rose and she just... stopped talking to him.
"I was telling her, I introduced the ghosting concept," Scarlett told the Today show crew. "It really makes the other person feel terrible."
She's trying to raise a human who isn't a "mean girl," even if that human happens to have a mom who is a literal superhero.
Cosmo Jost: The Set Baby
Then there’s Cosmo. Born in August 2021, his arrival was classic Colin Jost—short, funny, and a little bit chaotic. They kept the pregnancy a total secret. Then, out of nowhere, Colin posts on Instagram: "Ok ok we had a baby. His name is Cosmo. We love him very much."
He’s four now.
According to Scarlett, Cosmo was the "set baby" while she was filming Wes Anderson’s Asteroid City. She joked that nobody on the cast actually cared about her; they just wanted to know where the baby was. Tom Hanks and Bryan Cranston? Just fans of Cosmo, basically.
The Battle for Privacy (and iPhones)
If you're looking for photos of scarlett johansson children on her Instagram, you’re going to be looking for a long time. She doesn't have social media. Like, at all.

She has been very vocal about why she keeps her kids out of the public eye. She’s seen the "massive loss" that comes with being recognizable, and she wants Rose and Cosmo to choose that for themselves when they're older—not have it chosen for them before they can even read.
Even recently, at the 2025 Toronto International Film Festival, she talked about the "pressure" of getting Rose an iPhone. She’s resisting it as long as possible. It’s a struggle every parent has, but when your face is on every billboard in Times Square, that digital boundary feels a lot more urgent.
The "Rude" School Schedule
One of the most human things Scarlett has said lately was her rant about back-to-school season. We’ve all been there. She called her daughter’s school "rude" for starting the day right after Labor Day.
"I was not prepared," she told E! News on a red carpet.
It’s that kind of honesty—the "I’m a billionaire actress but I still haven't bought school supplies"—that makes people love her. She’s juggling a directorial debut (Eleanor the Great) and a massive movie career while trying to make sure her 4-year-old doesn't eat something off the floor and her 11-year-old understands basic social etiquette.
How They Balance a Blended Family
Colin Jost is, by all accounts, a great stepdad. Scarlett has mentioned that the two siblings get along well, even if they are in completely different stages of life. During the summer of 2024, they spent a lot of time together, which helped the bond between the "headstrong" Rose and the "gregarious" Cosmo.
Scarlett’s approach to parenting seems to be built on three pillars:

- Routine: She says her kids "thrive on it," even when it’s hard to maintain with her schedule.
- Communication: Sharing responsibilities with Colin to "close the gap" on the parenting guilt.
- Respect: Teaching them to respect the work she does, but also respecting their right to be anonymous kids.
It’s not perfect. She’s admitted to feeling the "mom guilt" just like anyone else. When she’s at work, she feels like she’s failing at home; when she’s at home, she feels like she’s missing things at work.
But honestly? Seeing a celebrity of her stature admit that the "terrible twos" (and now the "terrible fours") are "tackling her" physically is pretty refreshing.
What’s Next for the Johansson-Jost Crew?
As we move into 2026, expect Scarlett to stay just as tight-lipped. You’ll hear the funny anecdotes on talk shows—mostly about the "weird faces" her mother-in-law makes about Cosmo’s name—but don't expect a family reality show.
If you're looking to apply some of her "pro-privacy" logic to your own life, here are a few things to consider:
- The "Wait on the Tech" Rule: Even if you aren't an Avenger, delaying social media and smartphones can help kids develop a sense of self without the "likes."
- Routine Over Everything: If a kid as busy as Rose Dauriac can thrive on a routine, most kids can.
- Be Honest About the Struggle: Admitting that back-to-school is "rude" or that parenting is "hectic" doesn't make you a bad parent—it makes you a real one.
Scarlett might be the Black Widow, but at the end of the day, she’s just another mom trying to survive a Tuesday.
