Teigen and Legend have been married for almost 9 years and have two children, Luna and Miles. “The past few years have been a blur of emotions to say the least, but joy has filled our home and hearts again,” wrote Teigen, 36, who appeared to be referring to her miscarriage in 2020. After the miscarriage, Teigen spoke openly about the experience her, sharing the immense shock and pain she and her husband suffered. Her decision to share the news was seen as a blow against a longstanding culture of silence about pregnancy loss, despite the fact that 10% to 25% of known pregnancies end in miscarriage, according to the American Pregnancy Association. The couple previously said their first 2 children were conceived through IVF, and in her announcement Wednesday, Teigen said the new baby is on the way “1 billion shots later.” Teigan was hesitant to announce her pregnancy, she said. “Each appointment I would say to myself, ‘ok if it’s healthy today I’ll announce,’ but then I breathe a sigh of relief hearing a heartbeat and decide I’m still too nervous,” she wrote. “Ok, hey,” he wrote, “it’s too hard to keep it that long!” CNN’s Alisha Ebrahimji contributed to this report.
