She's a Lifestyle Blogger
Katherine has a self-titled lifestyle website, where she writes all about fashion, beauty, health, food, and animals. She's also a regular contributor to InStyle magazine and has served as a guest cohost on The View. "When we were growing up, my mom had my siblings and I write in a journal about the trips we would take and the different experiences we would have," Katherine previously told Girl Boss. "I hated doing it when I was younger . . . but I'm so happy that I have those diaries and I'm able to look back on what was in my mind what I was eight, or 14, or in college. Writing has always been a really big part of my life."
