Days after being admitted to the hospital, Chrissy Teigen has announced she and her husband John Legend have lost their baby.

The model, 34, shared the heartbreaking news with a lengthy post and series of images on social media on Wednesday night, saying their little boy, ‘Jack’, has died following ‘so many complications’.

Chrissy wrote in her post: ‘We are shocked and in the kind of deep pain you only hear about, the kind of pain we’ve never felt before. We were never able to stop the bleeding and give our baby the fluids he needed, despite bags and bags of blood transfusions. It just wasn’t enough’.

We are shocked and in the kind of deep pain you only hear about, the kind of pain we’ve never felt before. We were never able to stop the bleeding and give our baby the fluids he needed, despite bags and bags of blood transfusions. It just wasn’t enough. . . We never decide on our babies’ names until the last possible moment after they’re born, just before we leave the hospital.  But we, for some reason, had started to call this little guy in my belly Jack.  So he will always be Jack to us.  Jack worked so hard to be a part of our little family, and he will be, forever. . . To our Jack – I’m so sorry that the first few moments of your life were met with so many complications, that we couldn’t give you the home you needed to survive.  We will always love you. . . Thank you to everyone who has been sending us positive energy, thoughts and prayers.  We feel all of your love and truly appreciate you. . . We are so grateful for the life we have, for our wonderful babies Luna and Miles, for all the amazing things we’ve been able to experience.  But everyday can’t be full of sunshine.  On this darkest of days, we will grieve, we will cry our eyes out. But we will hug and love each other harder and get through it.

The devastating post included five black and white photos taken at the hospital, showing Chrissy crying on her bed as well as a shot showing her and John cradling their son.

On Monday, Chrissy, who conceived daughter Luna, four, and son Miles, two, through IVF with John, 41, revealed she was on ‘serious bed rest’ due to bleeding and said she was ‘about halfway through her pregnancy’, which is around 20 – 24 weeks. A stillbirth is when a baby is born dead at 24 weeks or later.

In a heartbreaking addition to the post, Chrissy revealed that ‘for some reason’ she and John had begun calling their unborn baby boy, ‘Jack’ despite only naming their other kids after they were born.

Losing a baby past 24 weeks is a stillbirth rather than a miscarriage. If a baby dies before 24 completed weeks, it’s known as a miscarriage or late foetal loss.

Shortly after breaking the tragic news to her followers, Teigen took to her Twitter page to further express her shock from the loss.

‘Driving home from the hospital with no baby. How can this be real,’ she wrote.

John also took to Twitter to share Chrissy’s post, while writing: ‘We love you, Jack’ alongside five black hearts.

The couple had revealed they were expecting their third child together in the music video for John’s new single, Wild, in August.

She had been hospitalized at Cedars-Sinai Medical Center in Los Angeles on Sunday night after enduring a month of bleeding due to having a weak placenta and had been at the hospital since.
