Hailey Bieber has opened up about the surprising and medically complicated circumstances surrounding her first pregnancy with son Jack Blues, whom she shares with husband Justin Bieber. The 28-year-old model and Rhode founder revealed that doctors had previously flagged a uterine condition that could pose serious challenges to conceiving and carrying a baby to term. Rather than following a careful medical plan, however, she found herself unexpectedly pregnant before any precautionary steps had been taken. The candid revelation offered a rare glimpse into a health journey that was far more complex than her public glow suggested.
Hailey shared the story on the SHE MD podcast on March 3, 2026, which she co-hosts with her OB-GYN, Dr. Thaïs Aliabadi, and Mary Alice Haney. “It was a complete surprise,” she said on the episode. “I had a uterine septum and Dr. Aliabadi kept telling me: ‘We’ll need to monitor that before you get pregnant because it could be a problem.’” She recalled being told that a minor surgical procedure might be necessary before she and Justin even began thinking about starting a family. Her casual response at the time was that she wasn’t planning on getting pregnant anytime soon, so they could address it when the moment came.
What happened next caught everyone off guard. “And then, almost miraculously, I got pregnant,” Hailey said. The news sent a ripple of alarm through her medical team, particularly Dr. Aliabadi, who had been closely tracking the septum situation. “And then she calls me and says: ‘I’m pregnant!’ My first reaction was: ‘No!’” the doctor recalled. It was a reaction born not from judgment but from genuine clinical concern, given everything she knew about the potential risks involved in Hailey’s specific case.
A uterine septum is a congenital anomaly in which a wall of connective and muscular tissue divides the uterine cavity into two sections, and it affects between one and three percent of women. Dr. Aliabadi explained the condition in detail on the podcast, describing it as a kind of internal wall that encroaches on the space where a baby needs to grow. “The septum can be mild, moderate, or severe. We measure it by ultrasound. If it is smaller than about a third of an inch, it is considered mild, and if it is between a third and just under an inch, it is moderate,” she said. Hailey’s septum fell into the moderate category, which placed her miscarriage risk at somewhere between 25 and 40 percent and her risk of preterm labor at between 10 and 20 percent.
The possibility of preterm birth was the part that frightened Hailey the most, and not just because of the statistics. Her mother, Kennya Baldwin, had experienced two preterm deliveries, with Hailey herself and with her sister Alaia. That family history added a deeply personal layer of anxiety on top of the already elevated medical risk. “I was convinced I would deliver early because of my mother’s history,” she admitted, “but my body had its own plan.” She took a PreTRM test to assess the likelihood of delivering before 37 weeks, which helped give her and her medical team a clearer picture of what to expect.
As the pregnancy progressed, something remarkable happened. The uterine septum began to stretch and expand as the baby grew, gradually resolving the obstruction rather than worsening it. “Fortunately, we realized that as the baby grew, the septum was widening. Everything was opening up and working the way it should,” Hailey explained. Dr. Aliabadi recalled being moved by her patient’s calm and unwavering belief that things would be okay despite the odds. “I will never forget how she looked at me while I was explaining the risks. She said: ‘You know what? I believe everything will be fine.’ I looked at her and responded: ‘I believe that too,’” the doctor said. In the end, mother and son came through healthy, and Hailey and Justin, who married in 2018, have been fully immersed in parenthood ever since. “I just love spending time with my son,” Hailey said at a Vogue event in Australia in February, speaking about her 18-month-old. “He grows so fast and everything passes so quickly. You become aware of how much you want to absorb every moment.”
Uterine septums are the most common structural uterine anomaly and yet they are frequently undetected until a woman experiences repeated pregnancy loss, which is part of why routine screening remains a topic of debate among OB-GYNs. The SHE MD podcast, which Hailey launched alongside Dr. Aliabadi, has become a notable platform for destigmatizing women’s health conversations that would have been considered too clinical or taboo for mainstream celebrity media just a decade ago. And for those wondering about the name Jack Blues Bieber, “Blues” is a subtle nod to Justin’s deep roots in R&B and soul music, a detail that makes the name feel a little more like a love letter than a simple baby name.
