James Van Der Beek revealed during Monday’s episode of “Dancing with the Stars” that his wife, Kimberly Brook, had suffered a miscarriage, one month after announcing they were expecting their sixth child.

“My wife Kimberly and I went through every expecting parent’s worst nightmare. We lost the baby,” the 42-year-old actor said on air, according to People. “The little soul that we had expected to welcome into our family took a shortcut to whatever lies beyond.”

“You never know why these things happen, that’s why I’ve been telling my kids,” the “Dawson’s Creek” star added. “All you know is that it brings you closer together, it breaks you open, it opens up your heart, it deepens your appreciation.”

Van Der Beek later dedicated his performance with partner Emma Slater to his 37-year-old wife.

“Kimberly, I’m dancing for you, I’m dancing for us,” he said.

Van Der Beek’s difficult evening continued, however, as he and Slater were eliminated from the competition. Taking to Instagram, the father of five reflected on his family’s loss.

“Wrecked. Devastated. In shock. 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,” Van Der Beek began.

“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 well-being. Grateful that she’s now recovering, but we’ve only just begun unpacking the layers of this one,” he continued.

Van Der Beek and Brook are parents to children Olivia, 9, Joshua, 7, Annabel Leah, 5, Emilia, 3, and Gwendolyn, whom they welcomed last June.

They wed in 2010.
