Honestly, if you follow Scarlett Johansson’s career, you know she’s basically the queen of the "clean break." She doesn’t do social media. She isn’t posting "get ready with me" videos from her bathroom. So, it’s no shocker that Scarlett Johansson kids—Rose Dorothy and Cosmo—are rarely seen in the wild.
While other Marvel stars might share the occasional birthday tribute on Instagram, Scarlett is out here playing the long game with her family’s privacy. She’s been vocal about how "precious" their anonymity is to her. It’s a deliberate choice.
The Two Very Different Worlds of Rose and Cosmo
Scarlett has two children from two different chapters of her life.
First, there’s Rose Dorothy Dauriac, born in late 2014. Rose is now 11 and is the daughter of Scarlett and her ex-husband, French journalist Romain Dauriac. Then you’ve got Cosmo Jost, who arrived in August 2021. He’s the son of her current husband, Saturday Night Live star Colin Jost.
Even though there's a seven-year age gap, Scarlett has mentioned that the two share a pretty sweet connection through their names. They’re both flowers. Rose is obvious, but "Cosmo" is also a colorful, daisy-like flower. Apparently, it took a minute for that connection to click with people, including Scarlett’s own mother-in-law, who reportedly kept suggesting the name "Cosimo" instead because it sounded more "recognizable."

Life with an 11-Year-Old: The Rose Dauriac Era
Raising a pre-teen in the public eye is a minefield. Scarlett has joked that once Rose hit age three, it felt like being in an "emotionally abusive relationship" because of the toddler sass. But now that Rose is 11, the conversations have shifted.
Earlier in 2025, Scarlett shared a story about teaching Rose about "ghosting." Apparently, a boy liked Rose, she wasn't into it, and she just stopped talking to him. Scarlett had to sit her down and explain why that’s actually a pretty brutal move. It’s those normal, "human" parenting moments that remind you Scarlett is just trying to navigate the same weird social hurdles as every other mom.
Rose also isn't exactly her mom's biggest fan when it comes to the Avengers. While she knows her mom is a "superhero," she actually finds the movies too violent. She’s way more interested in the hair and makeup or the princess-y side of things.
The Chaos of Toddlerhood with Cosmo Jost
Then there’s Cosmo. He’s three now, and according to Scarlett, he’s in that "H-O-T T-O-G-O" phase. She recently admitted that Chappell Roan's hit is basically on a loop in their house because Cosmo sings it 20 times a day.

Colin Jost has been surprisingly open (for them, anyway) about how much he loves being a dad. He’s known Rose since she was two, so he had a bit of a "preview" of what Scarlett was like as a mother before they had Cosmo.
Why the Secrecy Matters
Why does Scarlett Johansson keep her kids so hidden?
In a recent InStyle interview, she explained that once you're a public figure, you can "never stuff it back in the bottle." She wants her kids to have the choice to be public or private when they’re older. Rose actually asked if she could make videos for Scarlett’s skincare brand, The Outset, and Scarlett’s answer was basically: "You’re 10. No."
She’s also protective because of the way she grew up. Being a child actor is intense. She remembers the rejection, the crying on the subway after failed auditions. She doesn't seem to want that "performer" pressure on her kids unless they specifically seek it out as adults.

Balancing the Marvel Schedule and Parenting
It’s not all red carpets and glitz. Scarlett has talked about the "mom guilt" that hits when she’s filming. When she was working on Jurassic World Rebirth, she was able to bring the family along because it was summertime. But for other projects, like her directorial debut Eleanor the Great, she’s had to rely heavily on two "wonderful babysitters" and a very strict routine.
She’s the first to admit she’s a control freak. She likes her routine. She likes her kids to have a routine. And sometimes, that means she has to miss out on certain work events just to be home for bedtime.
Actionable Insights for Fans and Parents
If you’re looking to follow Scarlett’s lead on privacy or just want to know how she manages the juggle, here are a few takeaways:
- Establish Digital Boundaries: Like Scarlett, you don't have to share every milestone. Keeping some things "just for the family" can preserve a sense of normalcy.
- The "Flower Name" Strategy: If you're looking for cohesive sibling names that aren't too "on the nose," botanical names like Rose and Cosmo offer a subtle, stylish link.
- Honesty About the Struggle: Even with all the money in the world, the "working parent guilt" is real. Communicating with your partner and delegating (when possible) is the only way to stay sane.
- Wait for Consent: Giving your kids the "anonymity" of childhood allows them to build their own identity before the internet does it for them.
Scarlett and Colin seem to have found a groove that works for their blended family. It’s a mix of New York cynicism, SNL humor, and a very fierce, protective wall around the two people who matter most to them.
