Hilary Duff and her boyfriend Mathew Koma are expecting a baby girl together.

Duff told James Corden that her 6-year-old son, Luca, wants to name the baby "Cafont Croissant."

Corden and Duff agreed the name suggestion was actually pretty good.

Hilary Duff’s son is already pretty good at being a big brother. Duff revealed last week that she and boyfriend Matthew Koma are expecting a baby girl, and on Monday she shared that her 6-year-old son, Luca, knows just what he wants to name her.

"Luca thinks Cafont Croissant is, like, the coolest name," Duff told James Corden on The Late Late Show. "When I just refer to it as 'Cafont,' and I'm like, 'That would be so cool, nobody at school’s gonna be named Cafont,' he's like, 'Croissant. Cafont Croissant.' It, like, goes together, there's no separating the two."See the rest of the story at Business InsiderNOW WATCH: Sneaky ways Costco gets you to buy moreSee Also:39 foods that contain almost zero calories9 reasons you're tired all the time that have nothing to do with being lazyTurns out how attractive you appear has a lot to do with the way you walk
