The 28-year-old singer's education suffered because she was brought up in a strict Christian household who did not believed in public education, reported Contactmusic.
"I have a problem in reading. I was not going to great schools, because my parents did not believe in public education. They wanted the education to be influenced by their religion, so I was going to these halfway education-slash-Christian schools that were like pop up shop style education," said Perry.
She doesn't blame her parents and thanks her mother, Mary Hudson, for being a great teacher.
