Collin Gosselin sends cryptic signal to mom Kate after claims she’s ‘spiraling’ over his upcoming memoir

Collin Gosselin sent a thinly-veiled message to his mother weeks after announcing his upcoming memoir about growing up on reality television.

Collin, 22, shared a New York Post headline about Kate, 51, on his Instagram stories over the weekend, which read, “Kate Gosselin ‘spiraling’ ahead of estranged son Collin’s bombshell memoir: ‘She knows it’s about to hit the fan.'”

He blurred out his mother’s face, and shared a comment from a follower that said, “What’s done in darkness will always come to light,” according to People magazine.

Kate, 51, is reportedly “spiraling” over what her estranged son may reveal in his memoir, “In the Shadow of Eight: Surviving the Reality of My Childhood.”

“Kate had no idea this book was in the works,” a source told Daily Mail before acknowledging that “Collin hasn’t spoken to his mother since she abandoned him in an institution as a young child.”

“She didn’t expect any of this to ever come out. Now she’s spiraling because she knows it’s about to hit the fan.”

“Jon & Kate Plus 8” aired on TLC from 2007-09, when the former couple divorced. One year later, the show was rebranded as “Kate Plus 8,” which ran until 2017.

Collin was allegedly diagnosed with a behavioral disorder and, at 12-years-old, Kate sent him to the Fairmount Behavioral Health System — a psychiatric hospital located in Philadelphia. 

“I was not able, with my own resources here, to meet his needs,” Kate said during an episode of “Kate Plus 8.” Meanwhile, “Kate Plus 8” continued to air with the seven other children. Jon claimed he didn’t know that Collin had been sent to a behavioral institute until he was eating lunch with the kids one day and Collin was absent. 

At the time, Kate had full custody of the children and insisted she didn’t have to tell her estranged husband where Collin was because of a court order.

While Kate has allegedly told people that there are “zero facts” surrounding Collin’s claims, he reportedly has “the evidence to back everything up.”

“Kate can’t stop this book from coming out but I have no doubt she wishes she could,” the insider said.

Collin’s sextuplet siblings — Aaden, Alexis, Hannah, Joel and Leah — and twin sisters Cara and Madelyn, were also reportedly blindsided by the memoir.

The siblings allegedly don’t “really know the truth of what happened to him” aside from what their mother relayed, the source said.

Kate’s representatives did not immediately respond to Fox News Digital’s request for comment.

Earlier this month, Collin revealed his tell-all was set for an October release, and featured an image from his childhood with his mother covering his mouth with her hand.

“For a long time, I wasn’t sure I’d ever tell this story.
Growing up, millions of people watched my life on television,” he wrote.

“People felt like they knew me. They knew my family. They watched me grow up. But there was so much they never saw.
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.”

Collin added, “Writing this book forced me to revisit some of the hardest moments of my life, but it also gave me something I’ve been searching for for a long time: my voice.
This isn’t the story people think they know. It’s the story I’ve lived.”
