The 39-year-old Saturday Night Live star broke the news Sunday, August 15, during his performance in Ridgefield, Connecticut. "We're having a baby," she said during the show. "It is exciting."
The 36-year-old Black Widow star sparked pregnancy rumors in June after skipping several in-person promotional events for the film, while her virtual interviews were all close-ups.
The newest addition to the family will be Johansson's second child; She is also the mother of Rose, a 6-year-old girl, whom she shares with her ex-husband Romain Dauriac.
Johansson and Jost got married last October after three years of dating. The couple met on the SNL set in 2006, but were not romantically linked until May 2017, when they were seen kissing at an after party (a few months after Johansson filed for divorce from Dauriac).
Johansson called Jost "the love of my life" while appearing on SNL in December 2019. Jost, 39, wrote about Johansson in his 2020 memoir, A Very Punchable Face: "I've met someone I love. And with whom I feel more comfortable than ever. "
