Hilaria Baldwin thinks this might her biggest baby yet.
The 34-year-old pregnant fitness guru took to Instagram on Thursday to compare her four pregnancies over the past five years with a collage and slideshow of bare baby-bump selfies.
Each snap features Hilaria posing in front of a full-length mirror in her bra and underwear, alongside the name of each of her children that she shares with her 60-year-old husband, Alec Baldwin. The clip kicks off with 4-year-old Carmen, followed by 2-year-old Rafael and 1-year-old Leonardo, and concluding with her current pregnancy, simply labeled "Baby."
"So many of you have asked for a belly comparison from my four pregnancies," she captioned the montage. "I feel like this one is the biggest? What do you think? #WeGotThis2018"
Hilaria updated the post, stating that she noticed "a lot of gender guessing," and added that they've "already announced it's another boy."
In November, the couple, who have been married since 2012, announced the gender of their fourth baby with a homemade cake reveal surrounded by their three children.
The mom of three is making the most of her time with her kids before the new addition arrives, as she shared a sweet snap earlier this week of her snuggling up with her babies, bump and all.
"This photo is one of my favorites I have of my kids," she wrote of the snap, which featured her children dog piling their mama. "I let them watch part of a movie yesterday and they all snuggled up and were holding hands! I hope I captured it well enough for you to see too...they are my pile of puppies...babe in the belly and all."
She added that they "may steal each other's toys and fight sometimes," but they are her "team."
