UPDATED: Chris Brown Faces Jail Time As Court Revokes His Probation

UPDATE: TMZ is reporting that:  The judge just REVOKED Chris Brown's probation, but the singer was not taken into custody. Instead, Brown has been released on his own recognizance, and was ordered to appear in court in August when the judge will determine whether he violated his probation.

In the meantime, Brown will have a chance to respond to the L.A. County D.A.'s allegations that he violated his probation.

Chris Brown is once again swimming in hot waters because the L.A. County District Attorney has filed legal documents asking the judge in the Rihanna beating case to REVOKE HIS PROBATION, based on charges filed against him in connection with a hit-and-run last May.  Brown was said to have left the scene without showing a California driver's license and proper insurance info.

And Brown isn't happy..because he just tweeted the following:

The D.A.'s legal docs claim Brown "willfully and unlawfully" broke the law in the hit-and-run case.

 And, law enforcement sources tell us, even if the L.A. City Attorney ultimately agrees to drop the hit-and-run case because the victim doesn't want Brown prosecuted, the D.A. will press on because Brown has a duty to obey all laws as a condition to his probation.

The D.A.'s documents asks the judge to revoke his probation and immediately remand him into custody.  But we've learned that's a standard request and when the D.A. goes to court today at 1:30 PM PT, they will not ask the judge to haul Chris to the pokey.

If the judge finds that Chris violated his probation, he faces 4 YEARS IN PRISON.
