Scarlett Johansson and Colin Jost Welcome First Child Together -- and It’s a Boy!

Scarlett Johansson and Colin Jost welcomed their first child together, a baby boy named Cosmo. The ‘SNL’ comedian took to Instagram to confirm the news on Wednesday. He wrote, ‘Ok ok we had a baby,’ and revealed the baby's unique name. Jost's post also included another message, requesting privacy, which he followed up by joking, ‘For all inquiries please contact our publicist [Michael Che.]’ It’s baby no. 2 for the Marvel star. She shares 6-year-old daughter Rose with her ex-husband, Romain Dauriac. Scarlett and Colin have been married since last fall. They became engaged in 2019 following two years of dating. She recently told ET it was ‘really significant’ to have Colin by her side throughout the pandemic.
