CeeLo Green Getting High Grades for Sobriety

Exclusive Details

CeeLo Green's been a model citizen, and a sober one at that, for the last 19 months ... so his probation officer is asking the judge to cut him some major slack.

According to docs filed by the PO ... CeeLo exceeded the 360 hours of community service required -- spending 275.5 hours at MusiCares Foundation, and 94 hours with Volunteers of America-Veterans Center.

The docs also show he's peed clean urine in 10 drug and alcohol tests while attending all 52 AA meetings ... as the court ordered. The singer also earned glowing reviews from his therapist. He got 3 years probation for his no contest plea to furnishing ecstasy to a woman he was on a date with in 2012.

His PO wants to shift CeeLo to informal probation -- which means he still has to be on his best behavior, but does NOT have to check in with the probation office.

The judge has approved the modification.
