Scarlett recently appeared on The Kelly Clarkson Show, and during the interview, the actor spilled on how she and Colin landed on Cosmo's name.

"We just threw a bunch of letters together," she joked, before elaborating, "No, but I just really thought it was so charming and our friends all liked it."

Cosmo is Scarlett's second child, as she also shares 8-year-old Rose with ex-husband Romain Dauriac — and as it turns out, her two children's names share a thematic connection.

"Cosmo is a really sweet little flower that comes in different shades of orange and yellow," she said. "That's why my daughter liked it too."

Scarlett also confirmed Colin's previous claim that his mother wasn't a huge fan of Cosmo's name.

"Colin's mom had a little bit of a harder time with it," she said. "She kept suggesting other versions of it for a while and I was like, 'No he's already out, it's past that time.'"
