Hilary Duff has revealed that she's pregnant with her fourth baby in an adorable Christmas card photo.
The 36-year-old Lizzie McGuire alum announced that her family is growing in an incredibly sweet post shared on Instagram.
The first slide featured a humorous Christmas card snap of herself, her son, her two daughters, and her husband Matthew Koma, all sporting pajamas while sitting around in a bedroom.
In the photo, Duff is seen looking shocked while cradling her baby bump, while her four-year-old daughter Banks is hanging from the bed's rafters and her two-year-old daughter Mae is sitting on the ground with a guitar.
Her 11-year-old son Luca - whom she shares with ex-husband Mike Comrie - is sat in an armchair, holding a video game controller while Koma is posing on the bed.
Check out the announcement below:With a closer look, the frame around the photograph bears the words: "So much for a silent night. Love, the Duff-Bair-Comrie Crew."
The How I Met Your Father star also shared a second photo collage, featuring individual snaps of all three of her kids wearing pajamas, which read: "Buckle up Buttercups, we're adding one more to this crazy bunch!"
Koma - who shares Banks and Mae with Duff - also announced the exciting news on his Instagram page, reposting the family's holiday photo and writing: "Baby #4 is loading." He also hilariously tagged the location of his picture as "Vasectomy clinic".
Fans were delighted by the baby news, and many of Duff's famous friends flocked to the comment section to congratulate the couple.
Fellow Disney actress Alyson Stoner penned: "Just 8 more to complete the pack," while Pretty Little Liars star Lucy Hale said: "Ahh Congrats you guys!"
One fan heartfully penned: "I love how you included everyone’s name! Coming from a blended family, this feels significant! Thank you!", and another exclaimed: "YAAAAAY!!! MORE AWSOME HUMANS!!!" (sic)
A third added: "You’re kids are so lucky to have yall as their parents. Congratulations." (sic)
The A Cinderella Story actress married the 36-year-old music producer in 2019 after first striking up a romance in 2015 when they collaborated on Duff's 2015 album: Breathe In. Breathe Out.
The soon-to-be mother-of-four previously opened up about her husband in an interview with PEOPLE, sharing: "He was such an amazing dad right out the gate.
"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," she added.
She also spoke fondly of the chaos in their household, telling Shape Magazine: "I love my loud household with mayhem and the craziness and all the love and all the dirt. I love [parenting] with my husband. I love feeling like hugs and cuddles can make everything better. I love the pressure of being like, 'How the f*** are we going to make it through this day?'
"And making it through the day and being like, 'I don’t know how everyone is tucked in and fed and happy after all the things we’ve had to do today,'" she concluded.
Congratulations to Duff and Koma!
