Los Angeles prosecutors filed legal documents today seeking to revoke probation for Chris Brown after he was charged with misdemeanor hit-and-run and driving without a valid license last month.

Brown has been on felony probation since the 2009 beating of on again/off again girlfriend Rihanna, and if the judge finds that Chris violated his probation, he could face up to four years in prison.

The D.A.'s paperwork claims Brown "willfully and unlawfully" broke the law in the hit-and-run case, and they are asking that the judge revoke his probation and immediately remand him into custody. However, TMZ reports that it's a "standard request" and when prosecutors arrive at court this afternoon, they will not ask the judge to throw the R&B star in jail.

On May 12, Brown reportedly rear-ended a car and refused to provide the other driver with his insurance information at the time of the fender bender. The woman Brown hit (with his Range Rover, that is) showed Brown her license and information, but he didn't hand over his info -- his lawyer had it delivered to the other driver two days later.

Brown tweeted, "I did everything I was suppose to do during the so called hit n run, I provided the correct info. There were no injuries or damages. C'mon!!"
