Kate Gosselin and her son Collin Gosselin remain estranged years after he dropped bombshell abuse allegations against the matriarch.

Following Kate and Jon Gosselin's divorce, Collin opened up about his strained relationship with his mother during a July 2023 episode of Dark Side of the 2000s, appearing alongside his father and sister Hannah Gosselin.

A few days after his appearance on the Vice TV show, Collin's older sister Mady Gosselin accused him of physically threatening her and "every member of [her] immediate family," noting some incidents had happened in 2022.

"Further, I will never allow someone who has exhibited hateful and even violent behavior toward others based on their racial identity, gender identity, or religious beliefs to be in my life," Mady added.

Following the family members' explosive back-and-forth, Kate has repeatedly broken her silence to defend herself and address Collin's abuse allegations.

Kate Gosselin and her son Collin have been estranged for years.

In a lengthy statement in July 2023, Kate backed Mady's account while doubling down on her claims about Collin's mental health.

"My son Collin, whom I love with all my heart, has received multiple psychiatric diagnoses over the years," she wrote, in part. "For the safety of myself, his brothers and sisters and for his own well-being, he was placed in a facility following years of outpatient treatment which proved insufficient for his needs. The decision to admit him was made by emergency room doctors following one of his many attacks/outbursts – this one involving his use of a weapon."

Kate added, "Fast forward to the present day, and following Jon's removal of Collin from treatment, my son's unpredictable and violent behavior has sadly continued regularly towards Jon, Hannah and others around him."

The mom-of-eight also discussed Collin's "distorted perception of reality," which was "one of the many issues that he has always struggled with." She then called her son's allegations "complete fabrications" and stood by Mady's public defense of her.

"This is all I have to say on the matter, and I will not be discussing this subject any further at this time," she continued.

Kate Gosselin was previously married to Jon Gosselin.

The bitter family feud escalated after Collin claimed to The Sun that he had been abused by Kate during his childhood.

"My mother had a room built in our unfinished section of the storage basement," he claimed. "She had a room put up with cameras in it, a tiny window in the corner, and it was bolt-locked from the outside. It was like a containment room, literally, and it had a mattress on the floor, and that's how I lived."

Collin also claimed he was largely isolated from his siblings and stopped attending school.

While Kate did not directly respond to the allegations at the time, her attorney, Richard Puleo, said she "never wants to comment because she always knows that this gets taken out of context."

"She doesn't want to comment. Doesn't need to. The record speaks for itself," the representative added.

Jon and Kate Gosselin share eight children together.

Collin Gosselin's memoir will be released in October.

Collin confirmed he is releasing the memoir, In the Shadow of Eight: Surviving the Reality of My Childhood, on October 13.

"For a long time, I wasn't sure I'd ever tell this story. Growing up, millions of people watched my life on television. People felt like they knew me. They knew my family. They watched me grow up. But there was so much they never saw," he captioned the post. "For years, I kept those experiences to myself. Some because I was afraid. Some because I didn't think anyone would believe me. And some because I just wasn't ready."

Writing the book "forced" Collin to "revisit some of the hardest moments" of his life. At the same time, he shared how it also gave him "something [he has] been searching for for a long time: [his] voice."

"This isn't the story people think they know. It's the story I've lived," he added.

A follower wrote a comment on a video Kate posted on June 29, writing, "Sending you love, Kate! You know your truth and what a great mom you are."

Kate responded, "I'm fine. Nothing surprises me anymore in that department."

In another comment thread, one person shared, "As a Mom who has been constantly disparaged and lied about by her adult child with a skewed version of their childhood (fueled by their narcissistic parent), my heart is with you...Even though we know the truth and who we are, the hurt sneaks in once in a while."

She reiterated her claims about Collin's mental health, replying, "Thank you! YOU understand! Sadly, only parents who have a mentally ill child understand! It's so tough, and I'm learning that ppl have NO ability to understand unless they've been through it themselves."
