🧒 A Glimpse into Their Personalities & Family Dynamics
While Scarlett values her children’s privacy, she and Colin have occasionally shared sweet, funny glimpses into their kids’ budding personalities and their life at home.
- Rose: The “Bossy” and “Painfully Girly” Big Sister: Scarlett has described Rose as a “very sweet girl” who is also “a little bossy” and “very, very, very girly. Like painfully girly” . She’s growing up fast, and her mom is now navigating the challenges of having a tween, including a hectic back-to-school schedule that Scarlett jokingly called “rude” for starting right after Labor Day .
- Cosmo: The “Gregarious” Little Brother: Colin Jost has shared that his son is “funny” and can be “shy sometimes, but he’s a gregarious little guy” . The bond between the two siblings is strong, with Colin noting that Rose is a “very nice, loving sister” and that the two spent a lot of time together over the summer, getting along really well .
- A Happy, Blended Family: Colin Jost has been a part of Rose’s life since she was two years old, and he speaks fondly of his role as a stepfather. He once told The New York Times, “I think part of the reason I fell in love with [Scarlett] is she’s a great mom. You get to actually preview someone as a mom” . The family seems to have a loving and playful dynamic.
🤫 Scarlett’s Parenting Philosophy: Valuing Privacy Above All
If there is one central rule in Scarlett Johansson’s approach to parenting, it is the protection of her children’s anonymity. She has been very clear about her decision to raise Rose and Cosmo away from the public eye.
In a 2025 interview with InStyle, she explained, “The anonymity of my children is very precious to me” . She believes that once fame is unleashed, “you can never stuff it back in the bottle,” and she wants to preserve that normalcy for her kids until they are old enough to understand the consequences and make the choice for themselves .
This philosophy extends to her own life. Scarlett famously does not take photos with fans when she’s not working and has refused to join social media, stating that it “goes against [her] core values” to share so much of herself online . For her, the ability to simply “go and buy [your] own stuff at Duane Reade” is a gift she wants to give her children for as long as possible .
🎭 The Jost-Johansson Household: A Tale of Two Parenting Styles
It seems that even in a Hollywood power couple’s home, there’s a classic debate: who is better at reading bedtime stories? As it turns out, Scarlett and Colin have very different approaches, and they’re not afraid to playfully debate about it .
- Colin’s Approach: The SNL writer believes in letting the story speak for itself. He joked, “Actors do a whole acting thing, making it all about them, I feel I let the literature shine, the author speaks through me” .
- Scarlett’s Approach: The Oscar-nominated actress, unsurprisingly, brings her full performance to the task. She argued, “All I know is that before the children go to sleep, they want momma’s touch… They want to be soothed, brought into another land, I love to do all the voices” .
Despite their different techniques, the couple clearly shares a deep commitment to their family, creating a home filled with both laughter and heartfelt moments.
🎬 Scarlett the Mom vs. Scarlett the Movie Star
Balancing a demanding career with motherhood is a juggling act, and Scarlett has mastered the art of switching between her two most important roles. She told PEOPLE that, thankfully, to everybody at home, she’s “just mom.” She only becomes “the Black Widow when it’s convenient for my daughter, when she’s going to get something out of it” .
Her choices in films are sometimes influenced by her kids. When discussing her 2025 film Jurassic World: Rebirth, she noted that she would let her daughter see it despite it being scary, explaining that “it’s still appropriate for the family. You just gotta watch it through the crack in your fingers” . She even admitted that part of her reason for joining the franchise was to create a memorable movie-going experience for her children, just like she had when she saw the first Jurassic Park at age 10 .
