Zayn Malik used to read letters to his granddad.
The 24-year-old musician has said his grandfather - who was first-generation Pakistani - wasn't a particularly strong English speaker, and so the star used to sit and read his letters to him as a young child, which helped him develop his love for literature.
He said: "I read a lot as a kid. I don't know if I've ever said this, but my granddad used to get me to read letters. He's actually first-generation Pakistani. He was born in India, before India and Pakistan were divided. He came over, and he didn't speak a lot of English, so he used to get me to read his letters to him when I was, like, three or four. So I developed a real want to read things all the time. I would read books constantly as a child."
And the 'Dusk Till Dawn' hitmaker still has a passion for reading, and he admits he's obsessed with "conspiracy theory" books at the moment.
He added: "I'm still a reader. I've read a lot of different kinds of things. At the minute, I probably spend too much time reading conspiracy theory books that give my mind way too much information that I probably don't need. I like reading books about aliens and space."
Reading isn't Zayn's only hobby though, as he admits he's also got quite the green thumb and enjoys growing cucumbers and tomatoes in his garden.
Speaking to Fader magazine, the 'Pillowtalk' singer said: "I've been gardening a lot. I've got cucumber plants, tomato plants, onions, all kinds of crazy things growing. I just went to the local garden shop and bought seeds packets, read the instructions, and tried it at home. We've got some trees too - lemon trees and apple trees and grapes."
