Chrissy Teigen's mom mourns loss of grandson in heartbreaking goodbye video

Chrissy Teigen's mother, Vilailuck Teigen, broke her silence Thursday night about the devastating loss of her grandson, Jack.

The "Cravings" author shared the tragic news Wednesday night that, after being hospitalized for pregnancy complications, her third baby with husband John Legend didn't survive.

"My heart aches love you so much baby Jack," Vilailuck grieved, posting a heartbreaking video of her saying goodbye and mourning her grandson.

The video shows the elder Teigen approaching the nurse carrying the child as Legend is heard gently assuring, "It's OK."

Vilailuck breaks down in the video, sobbing as she caresses Jack, apologizing and offering prayers before leaning in to give him one last kiss.

The model's mom also included two photos showing her cradling him close to her chest.

Chrissy and Legend first announced they were expecting their third child together in August, breaking the news in the Grammy winner's "Wild" music video.

The family continually shared pregnancy updates with fans, even as Chrissy began experiencing complications and was put on mandatory bed rest.

The "Lip Sync Battle" host was hospitalized over the weekend but the baby ultimately didn't make it.

"We are shocked and in the kind of deep pain you only hear about, the kind of pain we’ve never felt before," Chrissy Teigen wrote about the loss. "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."

"Jack worked so hard to be a part of our little family," she added, "and he will be, forever."
