Scarlett Johansson revealed she faced criticism from her family after naming her 4-year-old son Cosmo, a name with Greek origins meaning 'order' and associated with celestial star power. Johansson, who shares Cosmo with her husband Colin Jost and has an 11-year-old daughter Rose from a previous relationship, explained that she initially kept the name private to avoid negative reactions. She recounted that her mother loved the name, recalling her third-grade crush named Cosmo, but her mother-in-law was less supportive, suggesting alternatives like Cosimo. Johansson shared that her family’s reactions ranged from support to skepticism, with Jost’s mother eventually accepting the name after meeting other relatives with similar names. Johansson also discussed the challenges of balancing her career and parenting, emphasizing the importance of routines and shared responsibilities, and shared insights about her children, including her conversation with her daughter about ghosting in relationships. The actress highlighted that most people get used to unique names once the baby is here and stressed that ultimately, the parents' love for the name is what matters most.
