Jon Gosselin has revealed that he has no idea where his 12-year-old son Collin is.

JON GOSSELIN HAS NO IDEA WHERE HIS SON COLLIN IS

“I have an idea where he is but I don’t really know where he is,” Gosselin, the former Jon & Kate Plus 8 star, told ET. The 39-year-old says his ext-wife Kate Gosselin refuses to tell him where Collin is. “I mean, I ask but she doesn’t tell me,” he says. “She doesn’t answer any of my texts.”

Kate currently has full legal custody of the estranged couple’s children, while Jon shares partial custody. He says he hasn’t seen Collin over a year and a half, and will be going to court to force Kate to tell him where his son is. Jon also claims that his other children have not seen Collin in a while either.

Kate holds that she enrolled Collin in a private school for special needs kids with behavioral problems. “Collin has special needs,” Kate has said. “[There’s] a fairly fluid diagnosis of what those needs are, but he needs to learn certain strategies to help him deal with things. This has been a struggle we’ve had for a very long time, and it’s one I’ve dealt with on my own.”

Jon says he didn’t think Collin was a special needs child. “I could see my kids getting annoyed with that because he’s the smartest and he does this, and he does that, and he always wants it his way,” he says. “He’s very particular, which could be bothersome. But, he’s very loving too. He was a cuddly kid as a baby.”

Collin can be seen in the trailer for the upcoming season of Kate Plus 8, which airs on TLC on Nov. 22. Watch the trailer below.
