CeeLo Green could go to jail for up to four years after prosecutors charged the musician with one count of furnishing a controlled substance on Monday afternoon. That charge stems from accusations that the "Voice" star slipped ecstasy into a 33-year-old woman's drink while the two were having dinner in Los Angeles in the summer of 2012. Green pleaded not guilty to the felony charge on Monday. Prosecutors have requested a bail of $30,000. 

Prosecutors declined to file any sexual assault or rape charges against Green, whose given name is Thomas DeCarlo Callaway. The unnamed woman accusing Green of drugging her has said that Green brought her back to his hotel room after dinner that night. The woman filed a police report last year accusing Green of assault. In a statement, Green's lawyer claimed partial victory based on the lack of assault charges: 

"We are pleased that the Los Angeles County District Attorney has completed its investigation and concluded that the evidence did not support the false and unfounded claims made over a year ago. 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 and it would be established that any relations were consensual. CeeLo had faith that if the true facts were known the District Attorney would reject those charges. As it relates to the one charge of furnishing or sharing ecstasy, Mr. Green will responsibly address that matter in a court of law but not comment on it further out of respect for the process.”

Green is due back in court on November 20th. Green has won 5 Grammy awards, and is scheduled to star in his own reality show in 2014.
