The former One Direction star took to Instagram on Saturday to share that he had injured his arm the previous evening. As a result, Louis has been forced to postpone several promotional appearances, including in-store album signings, so he can recuperate. "Thank you everyone that's listened to the new album so far, it means the world to me. The show last night in New York was incredible. Unfortunately on the way back I managed to fall and break my right arm pretty badly. So I'm gutted to say I'll have to reschedule the in-store signings next week.
