According to PageSix, the movie star is due anytime soon.
“Scarlett is actually due soon, I know she and Colin are thrilled.” Another insider added: “Scarlett is pregnant but has been keeping it very quiet. She has been keeping a very low profile.”
The actress has been sparking pregnancy rumours for a while now.
The new arrival will be Johansson’s second child. She previously welcomed daughter Rose, now 6, with ex-husband Romain Dauriac.
Johansson and the “Saturday Night Live” star, quietly tied the knot in October 2020 after three years of dating.
This will be Jost’s first child.
