And Colin Jost's post is just too funny!
Scarlett Johansson, 36, who is also a mom to daughter Rose Dorothy, 7, is now busy dotting on another beautiful baby. This time, it's a boy!

Johansson's rep Marcel Pariseau confirms the details with People, while Colin announced it via his Instagram account, "Ok, ok, we had a baby. His name is Cosmo. Privacy would be greatly appreciated. For all inquiries, please contact our publicist @chethinks." The last part being a prank on one of his closest friend Michael Che.
He also added the funny parenting hashtags #wegotawaywithitforalongtime, #nokidspolicy, and. #weregoingtodisneyworld.
Congratulations!
