You're likely familiar with the parents of Katherine Schwarzenegger.
But this is probably the first time you've heard of this 20-year old, which speaks to the new author's upbringing. Speaking to USA Today about Governor Arnold Schwarzenegger and mother Maria Shriver, the USC junior said:
"They were very protective of having us in the public eye when we were younger. We didn't go to Hollywood premieres. We practiced community service. We went to school and camp like normal kids."
Despite this healthy childhood, Katherine has written a book - "Rock What You've Got: Secrets to Loving Your Inner and Outer Beauty From Someone Who's Been There and Back," out tomorrow - which details the struggles she faced as a fourth grader.
"It was the first time I was aware of my body and compared what I looked like to what other girls looked like. It freaked me out," she says. "I want to let girls know they are not alone with the changes and doubts about their body."
Schwarzenegger stands 5'8" and is a size 6.
