But yesterday he revealed he injured it trying to pull off a flip on his skateboard while messing around with his bandmate Louis Tomlinson during rehearsals.
Zayn said: “We were in the studio and decided to do a bit of skating.
“But the floor in here isn’t the best.
“I fell off and the board went over my hand. It hurt so much.
“I was trying to do a trick and went flying. It was a bit stupid.”
Louis, 21, winced: “It makes me cringe thinking about it.”
