The 18-year-old singer insists the best-selling novel - which tells the story of a billionaire introducing a young college graduate to the world of bondage and kinky sex - is "educational" and he's found the tome helpful and "interesting".
He said: "I haven't bought it, but a female friend of mine was forcing me to read it out to her the other day.
"They were like, 'Just borrow this,' and I was like, 'Hmmm'. It seems interesting. I could probably learn from it, I don't know. I feel like it's an educational and interesting read."
Harry has become friends with a number of stars such as Kate Moss since he shot to fame with boy band One Direction, but he still finds it hard to believe that he is mixing with people like the supermodel.
Harry - who along with his bandmates shot to fame when they finished third on 'The X Factor' in 2010 - explained: "It's cool with people like Kate Moss, I wouldn't say I was really good mates with her, but it's weird for her to go, when I saw her at the Olympics, 'Oh Harry, come over.' That's a bit weird.
"Kate was probably getting massive at the same time my mum was giving birth, so it's a bit strange."
While Harry - who dated 32-year-old TV presenter Caroline Flack, 14 years his senior, earlier this year - has picked up a reputation as a bit of a party animal, he isn't worried about going "off the rails" because he is sure his friends and family would be able to "protect" him.
He added in an interview with The Sun newspaper: "As for becoming a hellraiser? I don't like going crazy, crazy. I like having fun but it's nice to just wake up in your own bed isn't it? I can see how you get dragged into the bad stuff, but I've got good friends around me.
"I don't look at myself as the Robbie Williams of the band. I don't think that kind of comparison is on any of our minds.
"If I did go off the rails, I think that to a degree a lot of people like to protect me, so they would step in. At the same time my close friends know I'm not stupid. They know I'm not going to do stupid stuff, so they like to just help me through."
