Madonna

The Queen of Pop was anything but a popular girl when she was in school and never felt comfortable around her classmates.

However, she claimed that her traumatic schooldays helped her to become successful as they established a life-long refusal to conform.

She said: "I was one of those people that people were mean to. When that happened, instead of being a doormat, I decided to emphasize my differences. I didn’t shave my legs. I had hair growing under my arms. I refused to wear makeup, or fit the ideal of what a conventionally pretty girl would look like."
