John Mellencamp said he is doing everything he can to support his daughter Teddy, who is being treated for stage 4 cancer.
The 74-year-old rocker said she speaks to the “Real Housewives of Beverly Hills” alum “every day” because “she’s been going through hell this past year.”
“She has 10 lesions on her brain…The lesions are not cancerous at this point, but they are still interfering with her thinking. They are in her frontal lobe,” he told People in a new interview published Saturday.
Teddy was able to have some of the lesions removed, but is still undergoing radiation therapy for the remaining lesions.
“The lesions are still there, but there is no cancer,” John explained. “But that doesn’t mean she’s free to go home. It just means she’s cancer-free at this point. So she’ll have to continue this treatment for many years.”
Teddy said as much on the Oct. 3 episode of his podcast Two Ts in a Pod with Tamra Judge, revealing that he plans to continue immunotherapy for at least a year, even though he no longer has “detectable cancer.”
John also told People that Teddy’s “personality changed” during his battle with cancer due to complications and side effects. “She’s the same person, but she’s not the same person. It’s not funny.”
John’s new revelation comes a day after he publicly urged Teddy to “come back home.”
The singer told viewers of Friday’s “Today” show that he’s “trying to convince” his girlfriend to move from Los Angeles to Indiana, but the 44-year-old Bravolebrity “won’t be able to do that.”
While speaking with Al Roker, Dylan Dreyer, and Craig Melvin, John also gave a worrying update about Teddi’s health, saying, “With the type of cancer she’s had for three years, you can’t say she’s cancer-free.”
“She feels good until she gets it (immunotherapy), then she feels like hell for about four days, and then she feels normal.”
Earlier this week, John opened up more on “The Joe Rogan Experience,” saying Teddy was “really sick.”
He added that she was “suffering” and “it’s not very fun.”
After the interview, Teddy admitted on his podcast Thursday that he is, in fact, “struggling with severe PTSD.”
Teddy was first diagnosed with stage 2 melanoma in 2022 and underwent more than 15 surgeries during his battle with the disease.
Several tumors were then discovered in his brain and he underwent emergency surgery in February 2025.
At the time, Teddy’s chances of survival were thought to be 50 percent, and his father began making plans for his burial.
But by October, Teddy’s stage 4 cancer, which had spread to his lungs, was “gone.”
“I’m not considered to be in remission or anything like that,” Teddy clarified to podcast listeners at the time. “When (doctors) say it works, it’s like, after a year, two years, three years, it’s considered remission.”
