Jon Gosselin is currently estranged from six of the eight children he shares with ex-wife Kate Gosselin. During an appearance on The Dr. Oz Show on Friday (March 5), the former reality TV star revealed none of his kids who remain in Kate's custody reached out to him following his COVID-19 diagnosis.

"Did you ever hear from any of the kids that are with Kate or are in college after it was made public that you had COVID, not just had COVID but were deathly ill, could've died?" Dr. Oz asked Jon.

"No, I didn't hear from them," he replied. While Mady, Cara, Alexis, Leah, Joel and Aaden live with Kate full time, Jon has custody of Hannah and Collin. "I think Hannah might have told Leah…No, I haven't heard anything from them," he added, explaining that "there's just a disconnect" between him and his six other children.

Jon also disclosed to Dr. Oz that he "can’t really reach out to them" because "there’s legalities...I can’t go to where they move, it would be trespassing." He then made a public plea to his estranged children, saying: "I love you, my door is always open, you're welcome anytime, there's no regrets or hard feelings or any of those negative things. You can always come see me or come see Hannah and Collin."

Jon was diagnosed with COVD-19 sometime last year. During another appearance on The Dr. Oz Show in January, he shared details from his experience with the highly contagious virus. "I was in a wheelchair. I had to wait in the ER," he said of arriving at the hospital. "It was packed, like the hospital was full, and then they put me on a gurney and put me in the hallway in the waiting room, so I could get a temporary room, and then once they evaluated me and once they drew my blood and did all my blood work, all of a sudden I'm getting antibiotics, steroids and a plasma antibody transfusion for COVID. It happened really fast."

The Jon and Kate Plus Eight star had "a really bad COVID pneumonia," however, he said he "didn't feel sick and I didn't feel pain" while he was hospitalized with the novel coronavirus. "When you went to move or do anything and you felt so weak and you wanted to pass out, it was really scary," he recalled. "If my urinals were full, I had to stand up and use the bathroom, I would fear it because I'm like, 'Oh my God, I'm going to pass out. I can't breathe.'"
