'Jon & Kate Plus 8' star Collin Gosselin accuses mom of trying to 'bury' him to ‘protect her reputation’

Collin Gosselin is taking aim at his estranged mother, Kate Gosselin, accusing the former reality TV star of trying to "bury" him to protect her public image as he makes allegations of childhood abuse in his new memoir, "In the Shadow of Eight." In an exclusive interview with Fox News Digital, the "Jon & Kate Plus 8" alum said he has not spoken to Kate since he was 13 and would need an apology and accountability before considering reconciliation.

"I'd like an apology, simply put, an apology and for her to admit, and just take accountability for what she did," Collin, 22, said.

In his memoir, "In the Shadow of Eight: Surviving the Reality of My Childhood," Collin alleged he endured physical abuse, isolation and forced psychiatric medication as a child.

He also compared his experience in a treatment facility to being sent to a juvenile detention center, saying it left lasting scars.

Collin said he held on to hope even during what he described as his darkest moments.
