Hilary Duff is going to be a mom again!

The singer, 36, is pregnant, expecting her fourth baby, her third with husband Matthew Koma, she announced on Instagram Tuesday.

The Lizzie McGuire alum shared a snap of her family's holiday card, which featured a photo of her three kids and Koma as they posed in a bedroom. Duff placed her hand on her baby bump, looking shocked while 4-year-old daughter Banks hung from the bed's rafters and 2½-year-old daughter Mae sat on the ground with a guitar.

Son Luca, 11, sat in an armchair, holding a video game controller while Koma posed on the bed, one eyebrow up.

"So much for silent nights," the card read. "Love, the Duff-Bair-Comrie Crew."

Duff also shared the back of her holiday card, which included solo shots of all three of her kids. "Buckle up Buttercups, we're adding one more to this crazy bunch!" the other side said.

Koma also shared the exciting news on his Instagram, reposting the family's holiday photo. "Baby #4 is loading..." he wrote, tagging the location of his picture as "Vasectomy clinic."

Duff shares her two daughters with Koma, and son Luca with ex-husband Mike Comrie.

The Younger actress previously spoke to PEOPLE about her life as a mom of three, sharing that she "loves this mayhem."

"I'm so in love with all my kids," said Duff.

"It's a learning curve to throw a newborn into the mix," she said after welcoming daughter Mae. "A lot of people have been like, 'That third kid really gets you.' And they're right!"

The former Disney star also opened up about having an amazing partner in Koma.

"He was such an amazing dad right out the gate," said Duff. "In this time of breastfeeding and craziness, he was like, 'I'm just going to be your assistant because I think that's how I'm going to be the most help to you in this timeframe.' He has this really amazing way of looking at the big picture where I'm very much like, right-here-right-now — and he zooms out."

The pair met when they collaborated on her 2015 album Breathe In. Breathe Out and dated on and off for years before locking it down. After welcoming Banks in 2018, Duff — who split from ex-husband Comrie in 2014 — began to warm up to tying the knot again.

After Duff sent Koma a screen-grab of a ring that caught her eye, he surprised her with a proposal in May 2019, and they wed that December.
