3. Britney Spears
Britney began her music career at the age of 11 on the Mickey Mouse’s New Club show. She was the most famous teenager since 1998, after she released the song Baby One More Time at only 16 years old.
Although her life seemed to be a real life fairy tale, Britney was marked by a traumatized childhood because of her alcoholic and violent father. At 18, she was already depressed and often dealt with panic attacks.
In 2007 she had a nervous breakdown in front of a crowd of paparazzi. While on drugs, she very publicly shaved her head.
