Karlie Kloss is now a mom of three!
The 33-year-old supermodel and her husband, Joshua Kushner, have welcomed their third child — a baby girl — born on September 18. Kushner, 40, announced the joyful news on Instagram on Saturday, September 20, with a sweet photo of their newborn daughter wrapped in a striped hospital blanket and wearing a tiny pink beanie.
"Rae Florence 9.18.2025 🤍," he wrote alongside the image. The couple, who were married in October 2018, are already parents to two sons: Levi, age 4, and Elijah, age 2.
Kloss first revealed they were expecting again back in March with a charming Instagram carousel that included her sons.
“Three’s a party 🥹🫶🎉,” she captioned the post, which featured four photos. In the first picture, Kloss holds Elijah in her arms, with the toddler resting just above her growing baby bump as she glances over her shoulder at the camera.
Other photos showed Kloss cradling her belly in jeans and a white top, her wedding ring visible, and striking a pose in a form-fitting black dress. The final shot captured a tender black-and-white moment of her two sons hugging each other.
Though Kloss tends to keep her family life away from the spotlight, she did open up during a May episode of the Aspire with Emma Grede podcast, offering a rare glimpse into her home life and partnership with Kushner.
"Josh, my husband, we've been together since I was 19. We've grown up together. He's always been my biggest champion," Kloss said, highlighting how supportive he’s been through both her career and her transition into motherhood.
"Especially in this adjustment into motherhood, he's been somebody who's like, 'Karlie, you cannot lose yourself. You will not be happy and then our children will feel that,' " she shared. "That's something I so appreciate, that he has been my mirror in that way."
Back in November 2023, Kloss spoke with PEOPLE and opened up about some of the physical challenges she faced during her second pregnancy, particularly with Elijah.
"Just being pregnant for nine months, I found my posture got so bad," she revealed. "So now, I'm relearning my whole anatomy and trying to fix it, straighten my back."
"My [fitness] routine has evolved," she added. "It's gotten more efficient. I feel like my philosophy has gotten much more about strength in sustainable ways. So I do light weights and also body weight exercises. I travel a lot still, so I don't always have a gym nearby."
