Cee Lo Green is reportedly under investigation after being accused of sexual battery, TMZ.com reports.

An unidentified woman has accused The Voice judge of spiking her drink with a drug, after which she woke up naked in a bed with Green in the room. The site also reports that Green has a history with the woman, whom he allegedly met at the 2012 Super Bowl and with whom he stayed in touch.

A former Voicecontestant, Terisa Griffin, has come to the singer's defense, saying that Green has always been nothing but a gentleman to her. "Cee Lo was extremely professional, not a drop of disrespect," she tells TMZ. "I was shocked to hear about the investigation."
