Opening up to the The Daily Dish about his father’s health, Taylor revealed that his dad had first been diagnosed in October.
“It’s in his throat, his esophagus, so it’s rough,” he said. “This is such a horrible disease. He doesn’t deserve this. He’s, like, the perfect man. He’s the perfect human being, never done a thing wrong in his life. So it just sucks.
Taylor also told PEOPLE about how tough it was to watch his father battle his illness.
“It’s the first time that I’m dealing with this, with any kind of family member having a disease,” he said, adding that “it’s rough because my father is kind of like my rock. He’s my best friend. Seeing him go through this is just awful.”
