Jon Gosselin is no longer a reality star, but that hasn’t stopped the dad of eight from speaking out about his ex and their brood on television. In a sneak preview of Jon’s “The Steve Harvey Show" interview, which airs Monday, the former “Jon and Kate Plus 8” lead shares some shocking claims about his custody arrangement with Kate Gosselin.

Jon, who gets to see his 11-year-old sextuplets and 15-year-old twins once a week for dinners and every other weekend, says he hasn’t seen all of his kids together in years.

“Most of the time I get four,” Jon, 38, explained of his custody situation during Harvey’s “Where Are They Now?” special. “I haven’t seen all of my kids together in about three years. I only get what I get … I have to go to the house and gets the kids. I have to go to the bus stop and get the kids. I pull up to the gate, and whoever comes down the driveway, that’s who I get.”

Because of his rocky relationship with Kate, whom he divorced after 10 years of marriage in 2009, Jon says he hasn’t seen one of his three sons in 18 months. “Now the kids are stuck in the middle between us … I haven’t seen my son in a year and a half. I don’t know why,” Jon says in the teaser. “I can’t talk to him. I have no communication.”

Kate has refused to speak out about Jon’s claims, but did confirm in an August 2015 interview that all of their children do not visit with their father. "I keep the peace,” Kate told In Touch Weekly of her relationship with Jon. “Some of the kids visit and some don't. That's for the best.”

While Jon did not clarify which son he hasn’t seen in over a year, a closer look at his Instagram page hints which sextuplet he most likely hasn’t spent time with. Jon’s posts, which mostly consist of shots of he and girlfriend Colleen Conrad and his DJ’s gigs, also contain images of his offspring. And while his sons Aaden and Joel are present in several shots, Collin, who is part of Gosselin sextuplets, is not. Jon’s photos also feature several shots of his daughters Maddie and Alexis, Hannah and Leah.
