John Legend and Chrissy Teigen are mourning the loss of their son.

The couple revealed that they lost their third child in a miscarriage after suffering pregnancy complications. In a message to her followers on social media, the 34-year-old mother of two shared the heartbreaking news on Wednesday, revealing that she was “never able to stop the bleeding” after being hospitalized in Los Angeles over the weekend.

Teigen posted a series of black-and-white photos including one of her sitting on a hospital bed while seemingly in tears and another of her cradling her baby, who the couple named Jack, while Legend kisses her shoulder.

“We are shocked and in the kind of deep pain you only hear about, the kind of pain we’ve never felt before,” Teigen wrote in her Instagram post. “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,” she continued. “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.”

Added Teigen, “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.”

Legend reposted Teigen’s statement on his own Twitter account, adding, “We love you, Jack 🖤🖤🖤🖤🖤.”

Following her Instagram post, Teigen also tweeted, “Driving home from the hospital with no baby. How can this be real.”

The couple, who are parents to daughter Luna, 4, and son Miles, 2, made their surprise pregnancy announcement in Legend’s video for “Wild” in August.

Teigen has been open about how she previously underwent in vitro fertilization to conceive their two children. A source told PEOPLE at the time that Teigen ″never thought it would be possible for Chrissy to get pregnant naturally″ and called the pregnancy a ″miracle.″

The couple received support from their celebrity friends and followers including Naomi Campbell, Gabrielle Union, Paris Hilton, Channing Tatum, and Kim Kardashian, who wrote, “We’re always here for you and love you guys so much.”
