"I don't have a relationship with Kate. There is no relationship. Text and email. That's it," John told ET last September about his estranged ex-wife, when he explained why he wasn't currently paying any child support for his eight kids. "[Kate and I] both support [the children] financially because she takes care of school and all that stuff, but I take care of the exact same things she takes care of. I buy their own groceries, they have their own groceries at my house, their own bedrooms, their own stuff, it's doubled."
"He lives his own life," Kate also told ET last September about the current status of their relationship. " I'm my kids' sole supporter, and I'm supporting them and concerned about their safety, and he lives his own life."
