Did Louis and Liam Prank a photographer?

The 1D guys are followed by paparazzi on a daily basis. But recently, Louis and Liam decided to have a little fun with it. While the photographers shoot them walking down the street, they have to walk backwards. So Liam and Louis decided they'd walk backwards instead so the photographers could walk forward while they took their pictures! We love how the guys understand that dealing with paparazzi is part of the whole package when it comes to fame and even have fun with it! But really, would you expect anything less?
