"Dawson's Creek" star James Van Der Beek revealed tragic news on "Dancing With the Stars" Monday night.
His wife Kimberly, pregnant with the couple's sixth child, suffered a miscarriage Sunday.
"It's every expectant parent's worst nightmare. We lost the baby," an emotional Van Der Beek said in his video opening before his second dance. "The little soul we expected to welcome into our family took the shortcut to whatever lies beyond."
The father of five was devastated by the news which he had announced on the show in October, even taking "DWTS" to the couple's first ultra-sound appointment.
"You never know why these things happen. That’s what I have been telling the kids," he said. "But it brings you closer together. It makes you more human."
Van Der Beek said he didn't expect to be dancing in the semifinals on Monday.
"Kimberly, from her hospital bed, said to me, 'I’m not done watching you dance.' " said Van Der Beek.
After telling his wife he loved her, Van Der Beek danced a tango to "Take Me to Church."
"I’m dancing for you. I’m dancing for us," he said. "Here we go."
He ended the routine sobbing audibly on the floor with his professional partner, Emma Slater.
After the dance ended, Van Der Beek took his crying daughter from the audience and held her.
"When tragedy strikes, it puts everything into perspective. I admire you so much," said judge Len Goodman.
"Wrecked. Devastated. In shock. That’s how we’re feeling right now," Van Der Beek wrote on Instagram. featuring a picture of his wife on Monday.
Van Der Beek alluded to a dangerous situation with Kimberly in the hospital, adding, "grateful that she’s now recovering,"
"But we’ve only just begun unpacking the layers of this one," he wrote. "As many of you have said, 'There are no words...' and it’s true. Which is why in a time like this it’s enough to know that you’re there. Grieving AND counting our blessings today."
In the October Instagram post announcing the pregnancy, Van Der Beek said the couple was, "thrilled beyond belief."
He admitted at the time that it was "something I NEVER thought we’d ever do" after going through several miscarriages.
"(Brook) and I have been through three of those first appointments to discover either no heartbeat, or no baby, and she wanted to share this moment," he wrote. "Happily, for us - this time- we walked out with tears of joy."
Van Der Beek said his family opened themselves up to help end shame surrounding miscarriage, "a word that needs a replacement" because "nobody failed to 'carry,' " he said.
Van Der Beek and Brook, who tied the knot in 2010, share daughters Olivia, 9, Annabel Leah, 5, Emilia, 3, Gwendolyn, 1, and son Joshua, 7.
