Katy Perry has never seen the 'Harry Potter' movies.
The 'Dark Horse' hitmaker is aware of the story of the boy wizard - who was played on the big screen in seven films by Daniel Radcliffe - but hasn't seen his adventures or read J.K. Rowling's books.
She admitted: "I know Harry Potter, but I've never read the books, nor have I seen the movies because growing up, I was not allowed to read the books."
The 31-year-old beauty - whose parents Keith and Mary Hudson are Christian pastors - thinks it is funny her latest fragrance is called Mad Potion because "enchanting" things were banned in her household.
She added to People magazine: "Growing up, I wasn't allowed to have any fantastical, enchanting stuff around me.
"It's funny that now I'm doing a little bit of a magic-potion-themed perfume."
Katy's father previously admitted he cried at one of the singer's concerts because he was so proud of her.
He told a congregation in Santa Fe Springs, California, in 2013: "I was at a concert of Katy's where there were 20,000. I'm watching this generation and they were going at it. It almost looked like church. I stood there and wept and kept on weeping and weeping. They're loving and worshiping the wrong thing."
