The pop star was a feisty teenager and her temper got her into trouble with several teachers.
Cheryl, who attended Walker Comprehensive School near her Newcastle home, said: "I was awful. They used to throw me out of class."
The `Fight for This Love` singer - whose second solo album `Messy Little Raindrops` is out next month - also revealed she was initially put off a career in showbiz because she didn`t think she was posh enough.
Cheryl didn`t feel as though she fitted in after she attended auditions for the Royal Ballet School`s two-week summer course when she was nine years old.
The 27-year-old star, who was only able to attend the dance course after a local newspaper raised the £300 she needed to get to the London auditions, said: "I wanted to go home straight away.
"Everyone was prim and proper and I was from a council estate. Their parents all had money and we struggled just to get the money to travel down to London. I felt I was the odd one out.
"I didn`t want to have to stand a certain way all my life and only eat salad."
But despite her worries Cheryl - who along with her four siblings was raised by her mother Joan and her painter-and-decorator father Gary - knew she was destined to perform.
Cheryl - who hit the big time after appearing on UK TV talent show `Popstars: The Rivals` in 2002 and becoming part of the chart-topping band Girls Aloud - added in her new book `Through My Eyes`: "Ever since I was a kid I`ve loved performing, being on stage, singing, dancing and showing off. There was just always something inside me, like, I knew there was no other option."
