The model, 34, is pregnant and expecting her third baby with husband Kyle Peterson, sharing the exciting news with a post on Instagram featuring snaps from her maternity shoot. In the photos, the soon-to-be mom of three smiled in an all white outfit that showed off her baby bump. In one picture, her daughter, 4, blew a sweet air kiss to her growing belly.
"Surprise! Coming spring 2026. 💙," she wrote in her caption.
In another post, the expectant mom shared some behind-the-scenes footage from her maternity shoot. In the short clip, DiDonato shared that she was "really proud" of herself for doing the photo shoot, encouraging fellow expecting moms to take one.
"I'm actually really proud of myself for doing this," she began. "I'll be honest pregnancy isn't a time I'm usually feeling my best, and I've always avoided maternity photo because of that, but this is likely my last pregnancy and I made myself show up and I love these photos."
"They feel important to me already, so if you're like me and tempted to skip it, take the photos," she said. "You won't regret it."
The new addition will join the couple's two other children: son Oliver and daughter Theadora, whom they affectionately call "Teddy." DiDonato and Peterson first became parents in November 2021 with the birth of their daughter. Two years later, the couple welcomed their son Oliver in May 2023.
Back in October 2024, the Victoria's Secret model shared her favorite part about motherhood. She shared it's the "extremely unique and deep emotional connection that I get to build and create with both of my children."
"The depth of the love and care that I feel for them is like nothing else in this world," she added. "I know it is cliché, but I just feel so lucky sometimes that I get to experience this type of relationship."

While DiDonato adores being a mom and considers it a "privilege," she admits that having a job she cares so deeply about comes with its challenges.
"The hardest part about motherhood for me is never being able to turn it off. No matter what I'm doing or who I am with, I am always thinking of my children," she shared at the time. "What should I be doing for them? What is coming up next? Do they need new clothes? Did I sign up for that after-school activity?"
DiDonato continued, "Being a mom is such a privilege, but it is a job that you cannot check out of. It is because you care so much and so deeply for your children, so you always want to do what is best for them, but sometimes you just want to be able to turn it off to rest or relax -- but I have not figured that out yet."
