John Mellencamp keeps showing up for daughter Teddi Mellencamp amid her cancer battle. "He has been beyond," Teddi, 44, said of her father during the Tuesday, July 29, appearance on "The Jamie Kern Lima Show" podcast. "The things that I wouldn't be capable of doing without my dad - not only for financial reasons." Teddi explained that she "used to take such pride" when it came to doing things without her famous father's help, but that all changed when she got sick. "With all of these medical treatments and everything, he has stepped in. He's helped me have a nurse," she continued.
