LOUIS TOMLINSON: Under Arrest!

Louis Tomlinson blew away his squeaky clean image on Saturday after assaulting a photographer at an L.A. airport, knocking him to the ground and nearly injuring a fan in the process.

The One Direction stud blew his top after he saw the paparazzo snapping pictures of him with gal pal Eleanor Calder, and went after the guy in a rage. Things got even weirder when Eleanor tried to stop a fan from taking snaps of that incident and got involved in a second brawl that ended with Louis knocking the girl to the ground.

Louis was arrested and booked for simple battery. He’s due in court in Los Angeles on March 29th. (Daily Mail)
