5 Fascinating Facts About Colin Jost’s Children
The family life of Colin Jost and Scarlett Johansson is intentionally kept out of the spotlight. Despite their fame, they have successfully managed to give their children a relatively normal and private upbringing. The following facts represent the most current and unique information available about Cosmo and Rose Dorothy.
1. Son Cosmo's Name Was Inspired by a "Gentle" Flower
The name of Colin and Scarlett’s son, Cosmo, is both unique and meaningful. Scarlett Johansson revealed that the name was inspired by a flower, the Cosmos, which is known for its beautiful, gentle nature. The name 'Cosmo' is also a nod to the universe and the star-studded nature of his mother's career. While the name initially caused some minor family disagreements on Colin’s side, it was eventually embraced by everyone.
2. Rose Dorothy Dauriac is a Big Sister and a Budding Music Critic
Rose Dorothy Dauriac, Scarlett Johansson's daughter from her marriage to Romain Dauriac, has fully embraced her role as a big sister to Cosmo. Rose's middle name, Dorothy, is a tribute to Scarlett's grandmother. In a recent interview, Scarlett shared a rare update, revealing that both Rose and Cosmo are fans of pop music, specifically mentioning that they both enjoy the music of artist Chappell Roan. This rare glimpse into their home life confirms that the children are growing up with a love for music, perhaps taking after their mother, who has also released music albums.
3. The Couple Maintains a Strict No-Photo Policy for Cosmo
In an age where celebrity parents often share their children's lives on social media, Colin Jost and Scarlett Johansson are fiercely protective of Cosmo's privacy. They have never shared a photo of their son on any social media platform, nor have they allowed him to be photographed in public. This high level of privacy is a deliberate choice to ensure Cosmo has a childhood free from the intense scrutiny that comes with being a celebrity child. The only public confirmation of his birth came via a simple, humorous post on Colin Jost’s Instagram: "Ok ok we had a baby. His name is Cosmo. We love him very much. Private privacy please."
4. Colin Jost is an Involved Stepfather to Rose Dorothy
Colin Jost is not only a father to Cosmo but also a dedicated stepfather to Rose Dorothy. While the details of their relationship are kept private, Jost has occasionally spoken about the challenges and joys of being a stepparent. He has been open about the learning curve of navigating family life with a child who was already a part of the family dynamic. His commitment to Rose is a testament to the strong, blended family unit he and Scarlett have built, a dynamic that is common in modern celebrity relationships.
5. The Family Life is Centered on New York, Away from Hollywood
Unlike many celebrity families who gravitate towards Los Angeles, Colin Jost and Scarlett Johansson maintain a strong base in New York City, where both were born and raised. Jost's career at Saturday Night Live is rooted in NYC, and the couple has extensive family ties there. This decision to remain on the East Coast helps them maintain a sense of normalcy and keeps their children closer to their extended family, away from the intense paparazzi culture of Hollywood. The couple’s low-key, New York-centric lifestyle is a key factor in their ability to keep their children’s lives so private.
The Future of the Jost-Johansson Family
As Colin Jost continues his successful run on SNL and Scarlett Johansson balances her career with motherhood, the focus remains firmly on their family. The couple has established a clear boundary between their public personas and their private lives as parents. Fans should not expect a sudden change in their approach; the rare, heartwarming anecdotes shared by the parents will likely remain the only windows into the lives of Cosmo and Rose Dorothy.
The children are growing up in a home filled with creativity, humor, and a strong sense of privacy. Rose is entering her pre-teen years, and Cosmo is quickly approaching school age, milestones that will undoubtedly bring new, private adventures for the family. The bond between the two children and their parents—Colin Jost and Scarlett Johansson—serves as a quiet, grounded center amidst the chaos of their high-profile careers, ensuring their kids have the most normal upbringing possible.
