"She's right. Unless you like a name, you probably shouldn't say anything about it. Nobody asked...who cares," Johansson said. "It does not affect your life at all. Nobody asked you."The TV star explained how, when she named her son, she didn't want to get a "weird face" from anyone.

"You're like, 'I have a baby in my stomach that I am birthing. I didn't ask what you thought,'" Bush Hager agreed."My third-grade crush was Cosmo. It had a great meaning for [my mom]," Johansson added. "My mother-in-law, a few days after, she goes, 'Cosimo is a name I can get behind. That's a recognizable name.' And I was like, 'We're not going to just insert an 'I.' That's what it is.'"

During the Friday, October 3, episode of TODAY With Jenna & Friends, the talk show host revealed she wishes she could expand her family."I would have had 22 children...not 22," she said, then corrected herself. "I had three, which feels like 21. I would have had one more. I would have rounded that out.""It's never too late, though!" guest co-host Justin Sylvester quipped."Yeah, it's probably too late. It feels like that ship has sailed," Jenna admitted.

"All I had to sort of think was, 'I want that.'"
