A male witness testified for the first time in the trial against R'n'B star R. Kelly, who was accused of sexual abuse.
The man, who uses the pseudonym Louis in public, accused Kelly at a court hearing in New York on Monday of sexually abusing him at the age of 17.
Kelly invited him under the pretext to support him with his music.
Louis said he met Kelly in 2006.
The witness told the court that he was on the night shift in a fast food restaurant branch in Chicago when Kelly slipped him his phone number.
Kelly invited him to his house on the pretext that he could perform in his studio and maybe get some tips for the music industry.
"He asked me what I was willing to do for the music"
When he later met Kelly in his house, the singer took him to his garage and sexually abused him there.
"He asked me what I was willing to do for the music," said the witness.
He then asked Louis to keep what had happened to himself.
"We're a family now, brothers," Kelly said.
Kelly recorded later sexual acts on video.
Louis testified that Kelly asked him to call him "Daddy".
Similar reports were made by several women accusing Kelly of sexual harassment.
Louis does not appear as one of the alleged victims of Kelly in the indictment, but is one of the other witnesses for the prosecution.
Louis negotiated a deal with prosecutors after being convicted of bribery in February 2021.
He had offered money to a possible witness against Kelly - in the hope that he would “not cooperate with the federal prosecutor”.
Louis said he was concerned that the unnamed witness was in possession of sex recordings of him and Kelly.
The trial of R. Kelly began in mid-August.
The singer of the world hit "I Believe I Can Fly" was accused of sexual abuse of minors, kidnapping and bribery between 1994 and 2018, among other things.
The now 54-year-old with the real name Robert Sylvester Kelly rejects all allegations and has pleaded not guilty.
A jury made up of twelve jury members, seven men and five women, decides on Kelly's fate.
