Teddi Mellencamp's biggest hero is her dad. On Thursday night, Teddi and her dad John Mellencamp attended the iHeartRadio Music Awards. While there, the 74-year-old rocker was honored with the Icon Award, which his daughter got to present to him. During her presentation, Teddi got choked up when talking about her dad. As you know, the Real Housewives star has been battling cancer since 2022 (though last year she announced it has metastasized to her brain and lungs), and during that time she really leaned on her dad for support.
