Kate Gosselin claps back after estranged son Collin calls on her to take a lie detector test ahead of his bombshell memoir

Jon & Kate Plus 8 alum Kate Gosselin's estranged son Collin challenged her to take a lie detector test with him so they could set the record straight about alleged past abuse.

'Mom, if you're listening to this, we would ask about the zip ties [used to bind my hands and feet in a locked basement],' the 22-year-old former child star told Strange McKnights' podcast last Saturday.

'I would also let her ask questions like, "Were you ever violent towards your siblings? Did you ever put your hands on your siblings?" Stuff like that. I want to get into everything. And this is where we are both hooked up to lie detectors, heart monitors, everything.'

Collin added: 'I always say there's the truth and then there's the truth from Kate Gosselin's point of view. So let's just put it all out there.'

And as recently as Tuesday morning, the Gosselin Pressure Washing owner claimed his 51-year-old mother used to write in her diary that she 'had to pray to God to stop hitting' her then two-year-old toddler.

Collin - who boasts 190,000 Instagram/TikTok followers - added: 'This is why using my voice to put these things in the light is so important.'

Grand Central Publishing is set to release the homeschooled sextuplet's 304-page memoir Shadow of Eight: Surviving the Reality of My Childhood on October 13.

'Nothing surprises me anymore in that department,' Kate replied to a TikToker about her mother-son scandal.

'Sadly, only parents who have a mentally ill child understand!' the pediatric nurse replied to another fan.

'It's so tough and I'm learning that [people] have NO ability to understand unless they've been through it themselves.'

Collin has repeatedly denied suffering from bipolar disorder, autism, OCD, ADHD, ODD and PTSD - all of which Kate claimed he had when she sent him to the Fairmount Behavioral Health System in Philadelphia for 22 months spanning 2016-2018.

The tattoo-sleeved Gen-Zer previously blamed his mother for 'crushing' his dream of becoming a US Marine in 2023 by publicly posting about his 'multiple psychiatric diagnoses' and 'violent behavior' one month before he was dismissed from training for 'non-disclosure of pre-enlistment history.'

When a TikToker suggested Kate sue Collin for defamation, she scoffed: 'I can't [because] I'm a public figure. Rules are different unfortunately. Or I [definitely] would!'

'The rules are different for [people] in the public eye,' the 'stay-at-home dog mom' continued.

'I consulted a high power LA attorney (you've definitely heard of him) years ago when other [people] were putting crazy stuff out there and that's what he said. The courts don't honor it if you're in the public eye.'

The Daily Mail has reached out to both Gosselins' reps for comment, and has yet to hear back.

Kate also welcomed 22-year-old children Aaden, Alexis, Joel, and Leah as well as 25-year-old twin daughters Madelyn and Cara during her decade-long marriage to Jon Gosselin, which acrimoniously ended in 2009.

The 49-year-old DJ was granted full custody of Collin in 2018 and his 22-year-old sister Hannah in 2016, and he wed second wife Stephanie Lebo last November after five years of dating.

Jon & Kate Plus 8 aired for five seasons on TLC spanning 2007-2010, once amassing 9.8 million viewers with the fifth season premiere.

The North Carolina-based blonde produced and starred in her own spin-off Kate Plus 8, which ran for six seasons spanning 2010-2017 plus a 'College Bound' episode in 2019.

Kate has also appeared in Say Yes to the Dress (2008), co-hosted four episodes of The View (2009-2010), competed on Dancing with the Stars (2010), Celebrity Wife Swap (2013), The Apprentice (2015) and wrote three non-fiction books.

According to IMDb, Collin will compete in the fifth season of Special Forces: World's Toughest Test later this year after Kate only made it one episode on the Fox competition in 2023 due to a neck injury.

Last week, the empty nester showcased her bikini body in a paid partnership post for Matrix Reformed, a hormonal imbalance subscription service.
