Jon & Kate Plus 8 alum Collin Gosselin has a not-so-subtle message for his mother, Kate Gosselin, amid their ongoing estrangement and ahead of his tell-all memoir’s release.
Collin, 22, took to his Instagram Stories on Saturday, June 27, to repost a news report claiming that Kate, 51, was “spiraling” about the contents of her son’s forthcoming book. (In addition to Collin, Kate and ex-husband Jon Gosselin are parents of twins Mady and Cara, 25, and sextuplets Collin, Hannah, Alexis, Leah, Joel and Aaden, all 22.)
Collin’s social media activity also included a screenshot of a fan’s comment that read, “What’s done in darkness will always come to light.”
Us Weekly exclusively revealed the cover of Collin’s debut book, In the Shadow of Eight: Surviving the Reality of My Childhood, earlier this month. The memoir is set to look back on Collin’s childhood as a young reality TV star and his troubled relationship with Kate.
“This book is about truth, survival, resilience and finding my voice after years of being silenced,” Collin told Us. “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 Collin’s book announcement. She has denied her son’s previous accusations about his upbringing.
Elsewhere on Saturday, Collin shared footage from a new YouTube interview where he asked Kate to complete a lie detector test.
“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, referring to his social media invitation from September 2025. “I want to get into everything, and this is where we are both hooked up to lie detectors, heart monitors, everything. I mean, they test for everything and we can either ask each other questions or we can have an interviewer ask us questions.”
Kate and Jon Gosselin’s son Collin Gosselin is opening up about where he stands with his estranged siblings. “Unfortunately, it’s just not something that is easy for me to talk about,” Collin, 21, said in the Wednesday, August 20, TikTok live video, per People. “As you can see, I don’t post on Instagram, I don’t […]
Collin explained that he wants to take the test with Kate, who never publicly responded to his offer, because she allegedly has “been putting on this facade” on social media.
Sharing the clip to his Instagram Stories, Collin claimed, “This was a year ago and I’ve been stood up by my mom … again.”
As for In the Shadow of Eight, Collin noted on “StrangeMcKnights” that he’s currently “in the process” of writing the book.
“I’m working with a lady who is … helping me to construct this a little bit better,” he acknowledged, seemingly confirming that he hired a ghostwriter. “Honestly, going over these events and putting them on paper and drafting them is almost therapeutic in a way.”
