Jon & Kate Plus 8 alum Collin Gosselin, 22, renewed his push for a lie detector test with his estranged mom Kate Gosselin, 51, as his tell-all memoir “In the Shadow of Eight: Surviving the Reality of My Childhood” nears release.
Collin Gosselin didn’t just repost a headline about his mother’s state of mind—he circled back to the one thing he says would clear the air.
On Saturday, June 27, the 22-year-old Jon & Kate Plus 8 alum shared a set of Instagram Stories aimed at Kate Gosselin, 51. He reposted a news report claiming Kate was “spiraling” about the contents of his forthcoming book. In the same Stories. he also shared a screenshot of a fan comment reading. “What’s done in darkness will always come to light.”.
The memoir—Collin’s debut—has been kept in motion just enough to build suspense. Us Weekly exclusively revealed the cover of the book earlier this month. “In the Shadow of Eight: Surviving the Reality of My Childhood” is set to look back on Collin’s childhood as a young reality TV star and his troubled relationship with Kate. Collin has previously framed the project as a bid for truth: he told Us that “This book is about truth. survival. resilience and finding my voice after years of being silenced.” He added. “If my story helps even one person feel less alone or gives them the courage to tell their own. then every difficult page was worth writing.”.
Kate has not publicly addressed the book announcement. She has denied Collin’s previous accusations about his upbringing, keeping the dispute between them firmly public—without either side stepping forward to match the other sentence for sentence.
That refusal to meet halfway is exactly why Collin keeps returning to the lie detector idea.
Earlier on Saturday, Collin shared footage from a new YouTube interview. In it. he asked Kate to complete a lie detector test. saying he had invited her after putting the offer out on social media in September 2025. “I did just say on social media that I would like to invite my mom to do a lie detector test. ” Collin told “StrangeMcKnights” in an interview published on Saturday. He described a setup where both of them would be connected to “lie detectors. heart monitors. everything. ” explaining. “they test for everything and we can either ask each other questions or we can have an interviewer ask us questions.”.
In those same Instagram Stories, Collin claimed, “This was a year ago and I’ve been stood up by my mom … again.”
His long-running argument is also wrapped up in the idea that Kate is presenting a version of events that doesn’t match his own. In a separate appearance. Collin explained that he wanted to take the test with Kate—who never publicly responded to his offer—because he believes she allegedly has “been putting on this facade” on social media. He also suggested the test could move past the noise and land on something verifiable.
Collin’s push for reconciliation is still paired with distance. He has described his position with the rest of the family as limited and difficult to talk about. In a Wednesday. August 20. TikTok live video. Collin—22 at the time—said. per People. that “it’s just not something that is easy for me to talk about. ” adding that he does not post on Instagram and doesn’t say much publicly. He later confirmed he is not on speaking terms with his estranged siblings.
On “StrangeMcKnights,” Collin also addressed where the memoir stands. He said he is currently “in the process” of writing the book and that he’s working with a woman “helping me to construct this a little bit better. ” seemingly confirming he hired a ghostwriter. He said. “Honestly. going over these events and putting them on paper and drafting them is almost therapeutic in a way.”.
The facts line up starkly: Collin has framed his book as a survival story and a search for truth. Kate has denied his accusations about his upbringing. and Collin has returned—publicly and repeatedly—to an offer he says has gone unanswered. With his memoir drawing closer, the lie detector invitation isn’t just a stunt. It’s the one mechanism he keeps pointing to as the difference between stories told at each other—and a moment of answers.

A lie detector doesn’t even work half the time, and people act like it’s court evidence??
So he’s still trying to get Kate to do some test like that would magically fix everything. Sounds like he’s just trying to control the narrative before the book drops.
Wait I thought Kate was the one that said she wanted the truth? So now Collin is doing all this “spiraling” reposting but the article says she hasn’t responded… so is it like she’s spiraling or he is? Kinda confused.
This family is addicted to cameras and drama. The lie detector thing just screams PR stunt to sell the memoir, and the quote about dark to light is honestly like something you’d see in a church Facebook post, not evidence.
