Black Widow star Scarlett Johansson is already mum to six-year-old daughter, Rose; the actress married Saturday Night Live star Colin Jost in a private ceremony in October 2020.
Jost, 39, shared news of the birth on Instagram to his 629,000 followers, saying: “Ok ok we had a baby. His name is Cosmo. We love him very much.” He added: “#wegotawaywithitforalongtime #nokidspolicy #we’regoingtodisneyworld” but did not post any photos, and said “privacy would be greatly appreciated”.
He jokingly directed inquiries to “our publicist @chethinks”, tagging his Saturday Night Live Weekend Update co-host Michael Che.
