Cee Lo Green has apologised for writing controversial tweets about rape which he later deleted.
He made the comments after his court case ended on Friday, where he pleaded no contest to giving a woman ecstasy.
The woman says she blacked out and woke up naked in the singer's bed, but prosecutors didn't charge him with any sexual offences.
He faced a backlash on Twitter after replying to users' comments and his account was briefly de-activated.
Once his account became active again, he tweeted: "I truly and deeply apologize for the comments attributed to me on Twitter. Those comments were idiotic, untrue and not what I believe."
In the controversial set of tweets Green, whose real name is Thomas DeCarlo Callaway, said "women who have really been raped REMEMBER!!!".
Another one, in reply to three users, said: "If someone is passed out they're not even WITH you consciously! so WITH Implies consent."
He then suggested that his no contest plea wasn't an admittance of guilt.
"So if I TRIED but did NOT succeed but the person said I DID then what really happened?"
The tweets replying to users about his court case appear to have been deleted, but some users posted screengrabs of them.
Before removing them and deactivating his account he had posted an initial apology saying: "I only intended on a healthy exchange to help heal those who love me from the pain I had already caused from this.
"Please forgive me as it was your support that got me thru this to begin with. I'd never condone the harm of any women. Thank you."
Green says he had consensual sex with the woman he gave ecstasy to after a dinner date in July 2012.
The judge sentenced the singer to three years of formal probation and 45 days of community service on drug charges.
He left the US version of The Voice after he was charged and CBS have now cancelled his reality show The Good Life.
Cee Lo Green began his music career in the 1990s as a rapper with hip-hop group Goodie Mob.
He then launched a solo career before finding success as part of the duo Gnarls Barkley after they released their first album together, St. Elsewhere, in 2006.
The album's first single, Crazy, became an worldwide hit.
He has also won five Grammys and various other music awards.
