The “Saturday Night Live” star revealed during an appearance on “Late Night With Seth Meyers” Thursday that his mom was “slightly thrown” by the couple naming their first child together Cosmo and that she “didn’t quite understand it.”
“I don’t know if she thought it was kind of like a hippie thing,” Jost quipped. “She would call us and say, after you know, like three or four days, she’d be like, ‘Cosmo.’”
“She’d be like, ‘And now is it final? Like, did you submit the birth certificate?’ And we’re like, ‘Oh yeah, we did that at the hospital,’” Jost said.
“She was like, ‘OK, interesting. Because I was reading that there’s also a name Cosimo with an ‘i,’ so that could also be an option. Maybe you call him Cosimo ― that’s his real name ― but then you can call him still Cosmo,’” he added.
Jost said that his mom came around to the unique moniker once she met “various members of the Italian community who have a lot of Cosmo relatives.”
“Then she would call, and she would say, ‘I met someone. They said their uncle’s name is Cosmo. So it is OK,’” the “SNL” star joked. “Then she goes, ‘There’s a patron saint called Cosmos, so that’s another option.’”
Johansson and Jost decided to pass on that suggestion as well, as Jost joked that the two “don’t need more worse options or variants on Cosmo.”
The “Black Widow” actor and “A Very Punchable Face” author first met at “SNL” in 2006, though they didn’t reconnect romance-wise until 2017. The two dated for three years before getting engaged in 2019 and later tying the knot in October 2020.
Jost confirmed in August that the newlyweds welcomed their first child together. Johansson also has a daughter, Rose Dorothy, from her prior marriage to French journalist Romain Dauriac.
