Kerr revealed on Snapchat in September that she was pregnant, expecting her fourth baby. Posing in a serene garden area, she revealed her bump in a Reformation x Christy Dawn crop top and jeans.

"So excited to announce baby no. 4," she captioned the first shot, later adding in another, "And it's a boy 🩵🩵🩵🩵."

Kerr is already mom to three boys: Myles, 4, and Hart, 5, with her Span Inc. CEO husband. She is also mom to son Flynn, 12, whom she shares with ex-husband Orlando Bloom, 46.

In another shot, Kerr showed four pairs of white shoes lined up against a wall. The white and yellow shoes each have a wooden block in front of them, showing which of her children they belong to, with a pair of tiny infant shoes finishing the line.

"#boymom💛," she captioned the shot.

Kerr told Vogue Australia last year that she always wanted a brood of boys. "I just love being a mother and I always wanted three boys, so I feel really blessed that I have three healthy boys," she said at the time.

She also told the magazine that her family is her "number-one priority," adding, "Then work, then my company, which is like another baby, and then, unfortunately, my friends, but it's not going to be like that forever."
