Collin Gosselin Tells Mom Kate She Can't Silence Him Over Memoir

Collin Gosselin is not backing down from his mother.

The former Jon & Kate Plus 8 star took to Instagram on Friday, Oct. 30, with a message aimed at Kate Gosselin, accusing her of trying to discredit him after the release of his memoir, In the Shadow of Eight: Surviving the Reality of My Childhood.

According to Collin, his mother "continues to spread lies in an attempt to conceal her abuse and break my spirit."

"It's not working," he wrote. "My determination to speak out for survivors will always be stronger than your attempts to silence me."

A No. 1 bestseller, again

The post was also a celebration. Collin shared a photo of himself holding his book inside a Barnes & Noble, wearing a cap that read "Be Kind," and announced that the memoir had landed at No. 1 on the New York Times Best Seller list for a second week.

"I am so deeply honored to announce that In the Shadow of Eight has once again earned the #1 spot," he wrote.

He thanked the readers who have backed him since the book came out, saying they had shown him "there is so much more love in this world than cruelty."

And he made clear he isn't planning to go quiet. "You will never stop my mission to protect and advocate for other victims of abuse," he wrote.

What Kate said before his post

Collin's message did not come out of nowhere.

Kate replied to supporters in the comments of one of her TikTok videos, a clip about her dog, ABC News reported on Wednesday, Oct. 14, the day after the book hit shelves on Tuesday, Oct. 13. When one fan wrote that she had "the support of so many," Kate answered, "Thank you so much," and added that "rational logical ppl or anyone who has dealt with mental illness understands what's going on here."

She did not name Collin or the book. When another commenter told her to "stay strong," she replied, "I am!"

Neither Kate nor TLC responded to ABC News' request for comment on Collin's interview.

In 2024, Kate's attorney, Richard Puleo, told The U.S. Sun that she did not believe she had intentionally harmed Collin, and that she had done what she did to protect herself and her family from what he described as troubled behavior.

What Collin alleges in the memoir

In the Shadow of Eight lays out Collin's account of his childhood after his parents' 2009 divorce. He alleges that his mother kept him in a locked basement room, restrained him with zip ties and isolated him from his father and siblings.

He also writes that, days before his 12th birthday, he was removed from home and placed in an institution with almost no contact with his family. His father later won his release through the courts, and Collin moved in with Jon and his sister Hannah.

According to the book, an independent psychological evaluation in 2023 found no mental health diagnoses.

These are Collin's allegations, and Kate's attorney has previously disputed his claims.

Jon Gosselin stands by his son

Collin was not alone on Friday. His father, Jon Gosselin, and stepmother, Stephanie, shared a joint Instagram post the same day praising him.

"You've turned some of the darkest chapters of your life into something that will help others," they wrote.

Where the family stands now

Collin is now in college studying finance, and he has said he still hopes to reconnect with his six siblings, who grew up alongside him on Jon & Kate Plus 8.

"I love you, I always have and always will," he wrote to them in the book.

For now, mother and son are telling two very different stories. Collin has a bestseller, his father's support and a message he says he will keep repeating.
