Hilaria Baldwin is no stranger to being pregnant, however, this fourth time appears to be just as magical and exciting as the first!

The mother of three shared a photo of herself in her underwear to celebrate another milestone with an Instagram photo Friday.

“Ciao first trimester!!!! 👋🏼🤢#BaldwinBabyBump4,” Baldwin, 33, wrote in the caption. “If you are new to following me, I post these from time to time while I’m pregnant. I try to stay as healthy as possible while pregnant but embrace slowing down, eating a bit more, and celebrating my changing body.”

“We all go through these changes while pregnant, it’s amazing, and I love to normalize it, rather than promoting being ashamed of gaining weight,” she continued. “If it offends you, you may unfollow. Negativity will be simply blocked ❤️.”

The fitness guru and husband Alec Baldwin announced they were expecting their fourth child together in early November. Baldwin shared oldest child, 22-year-old daughter Ireland Baldwin, with ex Kim Basinger.

“Our Baldwinitos are getting a new teammate this spring ❤️,” Hilaria captioned a family photo of herself, Alec, the family pup and the couple’s children Leonardo “Leo” Ángel Charles, 13 months, Rafael Thomas, 2, and Carmen Gabriela, 4.

They announced they were expecting a boy in a separate Instagram post, with Hilaria baking her family a cake to reveal the baby’s gender.
