Kristin Elizabeth Cavelleri, born January 14 1987, lived most of her childhood in Denver, Colorado. When her parents divorced due to irreconcilable differences, Kristin moved with her mom to Barrington, Illinois. After realizing she might be better in Laguna Beach, California where her father and brother, Mike, relocated. After a while, she moved in with her father and brother at Laguna.
After moving to Laguna, she briefly went to a Catholic school. She then transferred to Laguna High School. Which came at a good time, because soon after MTV producers came to Laguna High, to get people to audition for a new MTV reality show Laguna Beach: The Real OC. Kristen made the cut along with many others. Kristin had a fun time on the show. She dated Stephen and Talan. She also never made shy she hated Lauren Conrad, another star of the show and one of Stephen's best friends.
After that, only good things came. Going to uni, getting her own hosting gig (that sadly only went for two shows), making her film debut and many more acting and modeling roles. Kristin is most likely the most successful of anyone in Laguna Beach, making it in many films and TV roles.
