Hilary Duff and her musician boyfriend, Matthew Koma, announced on June 8 that they were pregnant with their first child together.

A few weeks later, Duff shared the news that they were expecting a baby girl.

The 30-year-old already has a six-year-old son, Luca, from a previous relationship. He had mixed feelings when he learned about his new baby sister.

Duff told AOL:

“The first conversation was pretty sad. He was like, ‘Why?’ Because it’s been just us for six years!”

Duff told AOL that in an effort to get her son excited about the newest addition, she has been keeping everything about the baby very lighthearted.


My sweet sweet boy. Oh the adventures we’ve had ?

She said Luca slowly but surely came around to the idea of having a little sister:

“I was like, ‘Dude, you have no idea. This is going to be a really good thing for our family. Mom has so much room in my heart for you and a sister and you’re going to have so much fun watching her grow and teaching her things.’ I also told him that babies are funny! I was like, ‘And I’m going to chase you around with her dirty diapers sometimes.’ And he was like, ‘Nooo!’ If I keep it lighthearted, then he has fun with it and I do think he’s excited. He’s touching my belly now and saying ‘goodbye’ to her when he goes to school.”

It has also been helpful for Luca to spend time with his newest cousin, Lulu.

Duff’s older sister, Haylie, recently welcomed a baby girl of her own. According to the actress, it’s making the transition easier for her young son:

“That has really helped. He’s like, ‘Well, I’m going to get one of those, too!'”

Luckily, as Duff told E! News earlier this week, her son is already “sweet and sensitive”— the perfect qualities for a soon-to-be big brother.

Duff shared a story of just how sweet her little boy can be:

“I’ll tell you something, this happened last year. When I’m filming “Younger” I’m [in NYC] for four months, and I try to make it home almost every weekend to see him because when he’s in school, he can’t miss.

So I happened to be home on a Friday or Monday or something like that, and I was just scrambling. It was just one of those mornings where everything that could have gone wrong, was wrong, and we were running late. I was burning the toast over and over again, and I think I had literally been through three pieces of toast. He was finishing his homework, and it was just crazy, and I was like, ‘Oh my God, I just suck right now.’ And I said it out loud. …

He said, ‘You don’t suck, you’re the best mommy. You’re doing the best you can do. And I really like burnt toast.’ I was like, ‘You are the sweetest child. I can’t even deal with you, thank you so much. I don’t know what I did to deserve you.'”

Luca’s baby sister is expected to arrive this fall.
