Does Justin think 1D copied him?

Justin's generally been pretty friendly towards 1D, but in a new interview he revealed that there was one thing they did that really put JB over the edge: copying his old signature side swooped hairstyle. Pointing at a pic of Liam's old hair, he said. "I mean, does that look a little familiar? Just a touch! It was like everyone had my hair and I felt everybody started to the same thing," he reveals. "So i needed to change it up a little up!"
