Van Der Beek broke the news on Dancing With The Stars which he is currently competing on.
“My wife Kimberly went through every expectant parent’s worst nightmare,” he said on the show before his performance. “We lost the baby.”
The former Dawson’s Creek star, who has five kids with his wife, followed up the announcement with an emotional post on Instagram.
“Wrecked. Devastated. In shock,” he wrote. “That’s how we’re feeling right now after the soul we thought were going to welcome into our family in April has taken a short cut to whatever lies beyond this life.
“We’ve been through this before, but never this late in the pregnancy, and never accompanied by such a scary, horrific threat to @vanderkimberly and her wellbeing. Grateful that she’s now recovering, but we’ve only just begun unpacking the layers of this one.”
It was during an October episode of Dancing With The Stars that Van Der Beek announced he and his wife were expecting their sixth child.
“Thrilled beyond belief to announce that another little bundle of joy has picked us to be their family,” he later wrote on Instagram. “We chose to have our first ultrasound on camera with our #DWTS crew capturing the result – something I NEVER thought we’d ever do.”
Tragically this is the fourth miscarriage Kimberly Van Der Beek has had, a fact she revealed on Instagram in September last year.
“I’ve had three miscarriages, all around 10 weeks gestation,” she wrote. “I let them all happen naturally.
“I had a loving husband, a compassionate birthing team and I felt spiritually grounded about them. And even in the best of circumstances, they all broke my heart. I was devastated every single time. After one of them, I sat in the shower crying for almost five hours.
“Thankfully I am fully at peace with them all now and have five children.”
