Bad boy Chris Brown crashed his car into a wall whilst tyring to escape aggressive paparazzi in Los Angeles, on the eve of the Grammy Awards.

The R&B singer told Beverly Hills police that photographers were chasing him right up until the crash on Saturday.

Police Sergeant Kurt Haefs said that the singer was not arrested at the scene and the wrecked car may have been towed away.

Media reports suggest the Don't Wake Me Up singer was driving a black Porsche.

The crash happened almost exactly four years to the day when Brown assaulted his then girlfriend, Rihanna, the night before the awards show in 2009.

Brown pleaded guilty in 2009 to beating and punching Rihanna and he faces ongoing legal battles as a result of the case.

It was not his week as a Los Angeles judge on Wednesday ordered a new report on the community service served to him as a result of the conviction, after allegations he logged his community service hours incorrectly.

Rihanna, who confessed that she has resumed dating Brown, accompanied him to his court hearing last week.
