8/29/2014 10:10 AM PDT

CeeLo Green just pled no contest in the case where a woman accused him of slipping her ecstasy ... and the plea allows him to maintain his innocence.

TMZ broke the story ... a woman claimed that she and the singer were at a downtown L.A. bar and the next thing she knew she was naked in his bed. The D.A. filed charges of furnishing ecstasy -- a felony. CeeLo just pled no contest to sharing ecstasy ... the difference being there is no underlying concession he slipped her anything. In other words, it was voluntary sharing.

As we previously reported ... the woman was no stranger to CeeLo ... they had been dating for months and he flew her out to L.A. and Vegas on several occasions to be with him. There were also witnesses in the bar who claimed she walked out looking fine.

The no contest plea is a felony ... but the plea allows him to maintain his innocence. CeeLo must perform 360 hours of community service at the MusiCares Foundation of the Recording Academy and attend 52 AA meetings with a private therapist. He's also on probation for 3 years.
