Hilary Duff’s 4 Kids: All About Luca, Banks, Mae and Townes

The couple share daughters Mae James, 2½, and Banks Violet, 5, and co-parent Duff’s oldest, Luca Cruz, 11, with her ex-husband, Mike Comrie.

Duff announced on Instagram that she was expecting her third child with Koma in December 2023 in her family’s Christmas card, which featured a photo of her cradling her stomach.

“So much for silent nights. Love, the Duff-Bair-Comrie Crew,” the front of the card read, while the back confirmed the news: “Buckle up Buttercups, we’re adding one more to this crazy bunch!”

Duff loves the “mayhem” of raising three kids, she told PEOPLE in a 2021 interview shortly after welcoming Mae.

“I have help, but babies just want their mom,” she said at the time. “Even Luca is still like, ‘Mom, Mom, Mom.’ Mom cooks the thing the right way, and Mom packs the bag the right way. It’s crazy.”

The “Come Clean” singer” also said that she is “so in love with all my kids” — and the busyness that comes with it.

“I love when everyone’s full of energy and the house is buzzing. You never know what the day is going to bring or what your kid’s going to say,” she told PEOPLE. “We’re in the thick of it, and it feels good.”
