Hilary Duff Reveals How Luca Feels About Upcoming Baby Sister & Shares His Unique Name Choice!

Hilary Duff opened up about how her son Luca, 6, is reacting to the news that she’s pregnant and expecting a baby girl with her boyfriend Matthew Koma.

“The beginning was a little, a little a… he was surprised. And now he’s warming up to the idea,” Hilary said during her appearance on The Late Late Show with James Corden on Monday (June 11).

“He told his friend at school the other day that he’s having a sister that’s part red-butt monkey. So we’ll see! It’ll be a first. That’ll be really cool,” Hilary continued.

“We’re up for any kind of suggestions, but Luca thinks ‘Cofant Croissant’ is like, the coolest name. There would be no confusion. And when I just refer to it as ‘Cofant,’ and I’m like, ‘That would be so cool, no one at school’s going to be named Cofant,’ He’s like ‘Croissant. Cofant Croissant.’ It goes together. There’s no separating the two,” Hilary added.
