Collin Gosselin Dishes on Upcoming Memoir, Plans to Expose Mom Kate With ‘Proof’

Collin Gosselin is planning to tell all in a new book.

“There were always things that I felt were important to be out there,” Jon & Kate Plus 8 alum, 21, told The Sun in an article published on Sunday, October 5.

The Sun reports that Collin plans to write about being allegedly abused by his mother, Kate Gosselin. The entrepreneur explained that he wants his siblings — fellow sextuplets Hannah, Leah, Alexis, Aaden, and Joel, and older twin sisters, Mady and Cara, 24 — to read his side of the story.

“I am going to release financial documents,” he told the outlet. “I am going to release everything so that they at least have the proof to build their own perspective. I am going to release proof that puts everything there so people can think for themselves.”

The former TLC star — who told The Sun in 2024 that Kate, 50, “had zip-tied my hands and feet together” and “locked” him in the basement on multiple occasions — will also chronicle his time at the Fairmont Behavioral Health Institute in Philadelphia.

As Star previously reported, Collin accused Kate of abuse in the July 2023 docuseries The Dark Side of the 2000s, alleging his mother sent him away when he was 12 and “started to tell people what was going on at home.”

In 2018, Kate’s ex-husband, Jon, 48, was granted sole custody of Collin and Hannah, and he removed his son from the facility.

Kate denied Collin’s allegations by taking to her Instagram a few days after the 2023 docuseries aired, claiming her son had “multiple psychiatric diagnoses” and said she institutionalized him “for the safety of myself, his brothers and sisters and for his own well-being.”
