It’s probably safe to assume that you know who Chris Pratt is at this point, but in case you are out-of-the-loop about Katherine Schwarzenegger, she is the author behind several books: 2010’s Rock What You’ve Got: Secrets to Loving Your Inner and Outer Beauty from Someone Who’s Been There and Back. She actually published these before graduating college, and later wrote 2014’s I Just Graduated . . . Now What? Additionally, she also wrote the children’s book Maverick and Me, based on a survival dog she rescued, which came out in 2017. As her last name would suggest, she is also the daughter of Arnold Schwarzenegger and Maria Shriver. Additionally, the 29-year-old author is also the grandniece of John F. Kennedy. So, she is a Kennedy too!
