The 29-year-old supermodel gave birth to her second child, a baby boy, with her fiancé, Hermann Nicoli, on Tuesday.
Swanepoel revealed the exciting news via Instagram Stories, sharing the first picture of her sweet newborn.
"Blessed," she wrote over the image, which showed the baby boy grasping onto her finger.
She later posted a pic of herself holding her little bundle of joy, captioning it, "Thank you so much for all the well wishes... Our little man was born this morning at home and he couldn’t be more perfect. 💕."
Swanepoel, who also shares 1-year-old son Anaca with Nicoli, announced she was expecting back in December. The blonde beauty revealed "Christmas came early" with a picture of herself cradling her baby bump in a green, off-the-shoulder dress.
