Louis Tomlinson has been arrested and granted bail in LA after a run in with paparazzi.
The 25 year old One Direction singer is due in court in three weeks over the row, which his lawyer says broke out after he was "provoked" by photographers.
His girlfriend Eleanor Calder is thought to have argued with onlookers who had started to film what was happening.
The couple had just arrived back from a holiday in Las Vegas.
Louis released his first solo single in December, featuring Steveo Aoki.
