But Scarlett Johansson’s baby boy may just have taken the top spot…
The actress finally revealed the reasoning behind her son, Cosmo’s name on The Kelly Clarkson Show.
She explained that she and her husband literally “threw a bunch of letters together. I just really thought it was charming and our friends liked it.”
However, she shared that other family members took some convincing: “Colin’s mom had a little bit of a harder time with it.”
“She kept suggesting other versions of it for a while. I was like, ‘He’s already here. He’s out. Like, it’s past that time,” Scarlett joked.
But it seems her daughter, Rose, 8, who she shares with ex-husband, Romain Dauraic, was a fan of the name.
“Cosmo is a really sweet little flower that comes in different shades of orange and yellow and stuff like that,” she added. “That’s why my daughter liked it too.”
