CeeLo Green has been charged with drugging a woman who also accused him last year of sexual assault. The woman says that, while eating together an at LA restaurant, Green put Ecstasy in her drink and then had sex with her. She says she woke up naked in bed, with Green in the room with her. An investigation was opened, and prosecutors ultimately declined to charge the singer with sexual assault due to insufficient evidence, NBC News reports. Green admitted to taking Ecstasy himself, but denied giving it to the woman. TMZ notes that Green and the woman had been dating for months at the time, and had been intimate in the past.
