Los Angeles prosecutors will charged Cee-Lo Green with giving Ecstasy to a woman who claimed the singer drugged her and had sex with her, but have declined to file charges of sexual assault against him, citing insufficient evidence, according to sources familiar with the case.

Green, whose real name is Thomas DeCarlo Callaway, was accused last year by a woman he dined with at a downtown Los Angeles sushi restaurant of placing Ecstasy, also known as MDMA or Molly, in her drink.

The woman later told Los Angeles Police detectives she woke up naked in bed in a room with the singer. The department opened an investigation into the woman’s allegations and consulted with prosecutors, who asked detectives to continue to seek evidence in the case.

Green faces a single count of ecstasy possession.  He is scheduled to make a court appearance in Department 30 at the downtown Los Angeles criminal courts building.
