Cee Lo Green has appeared in court accused of giving a woman ecstasy at a Los Angeles restaurant.
Prosecutors decided not to to file a rape charge against the Grammy-winning singer-songwriter and rapper because of insufficient evidence.
Green, 38, whose real name is Thomas DeCarlo Callaway, appeared in court hours after prosecutors charged him with one count of furnishing a controlled substance. He could face four years in prison if convicted.
Green spoke only once during the brief arraignment hearing to acknowledge he understood the court's scheduling of his case.
He sat in a front row of the court with his girlfriend while waiting for a bondsman to post his 30,000-dollar bail. His case is due back in court on November 20.
In a statement, his lawyer Blair Berk said Green was pleased that the rape charge was rejected and would address the ecstasy case in court.
She said any sexual contact between her client and the woman was consensual.
"Mr Green encouraged a full and complete investigation of those claims and he was confident once conducted he would be cleared of having any wrongful intent," Ms Berk said. She declined to comment further.
Green is the Grammy-winning singer of the hit Forget You and performed as part of the duo Gnarls Barkley. He appears as a judge on NBC's The Voice competition show. The network would not comment on the charge.
