Snooki
Someone as lively, as spunky, as eccentric, and as abrasive as Snooki obviously used to be a cheerleader back in high school. Even though she was immensely popular in high school, she was always self-conscious about her image. Snooki suffered from an eating disorder, which left her weighing only 80 pounds at one point.
Thankfully, she got over her eating disorder to become the colorful character we know today. She was launched into stardom after playing in Jersey Shore and its spin-off series. In 2013, she competed in the 13th season of Dancing with the Stars alongside partner Sasha Farber. The two came in eighth place, even though they were highly praised by the judges every time they appeared on stage.
