"Kyle is bipolar," Todd told E News, explaing that his son, who has been in and out of rehab, is now missing. "I will get him the help that he needs once we locate him. He left my mother's house and we've not seen him".
Todd explained that Kyle has been under a permanent guardianship since 2009 and added, "Police are looking for Kyle now."
Todd also responded to Kyle's allegation that he was using Kyle's mixed race baby, Chloe, for ratings. "That is not true. That is probably the most hurtful thing in the article," said Todd, who, along with his wife Julie, is raising Chloe.
As for why Kyle isn't on the show anymore, Todd said, "I didn't kick Kyle off the show. He refused to take his medication. He was hostile to the crew. He was hostile to other people on the show and you can't have that."
Kyle gave a interview to Daily Mail on Friday in which he blasted Todd's credibilty. "My dad is all about control. He's vindictive and manipulative. He's a snake and if there's a snake in the grass you don't know but hell it'll bite you when you go by."
Kyle, who claims he is sober now and has married a woman named Lexi, is going to court to get custody of his daughter back. "This show has been nothing but bad for me. At this point he's ruined me and he's ruined the other three kids he's had who are spoiled. But I'm not taking a chance on him ruining my daughter."
