Katherine Schwarzenegger poses for a portrait in Los Angeles March 17, 2011. Schwarzenegger is not your average 21 year-old college student. She is the first-born child of ex-California Governor and Hollywood movie star Arnold Schwarzenegger and his wife Maria Shriver. But in her own right, Katherine is an author, and she raises money for charities including her uncle Anthony Shriver's group, Best Buddies, a volunteer program to support people with intellectual and developmental disabilities.
