Miranda Kerr is pregnant! Model shares excitement over being a mom to 4 boys

Miranda Kerr is preparing to be a four-time boy mom.

The Australian model and entrepreneur, 40, announced Friday on — where else? — Snapchat that she is pregnant with her fourth son, who would be her third child with husband Evan Spiegel, who is the app's co-founder and CEO. She shares her firstborn child, Flynn Bloom, with ex-husband Orlando Bloom.

"So excited to announce baby number 4," she posted to her Snapchat story alongside a photo of herself in a cropped white lace shirt and bellbottoms, which accentuated her belly. "And it's a boy," she added in a second post.

Her final photo showed four pairs of white and (Snapchat) yellow sneakers lined up with blocks numbered one through four to depict her four sons.

Spiegel and Kerr welcomed their first son together, Hart Spiegel, in May 2018. Myles Spiegel came along over a year later in October 2019.

The business-minded former Victoria's Secret model — founder of the skincare brand KORA Organics — teased the Snapchat announcement on Instagram with a post showing her in a yellow-and-white dress and a caption that read, "Sharing some exciting news on Snap today 💛."

USA TODAY has reached out to reps for the couple for a statement.

Kerr and Spiegel had a backyard wedding at Spiegel's Los Angeles home in 2017, according to People. Youngest son Myles is 3 years old, while older brother Hart is 5. Flynn Bloom is 12 years old.
