This comes after Avenatti previously gave prosecutors a VHS tape that allegedly showed Kelly and an underage teenage girl engaged in sexual activity.
The jury in 2008 acquitted Kelly of child pornography charges that centred on a graphic video that prosecutors said showed him having sex with a girl as young as 13.
According to Newsweek, Greenberg told reporters on Saturday that he is confident Kelly will be able to produce the money eventually. Greenberg informed the judge that Kelly already turned over his passport and will not be contacting anyone under 18.
Until Kelly can come up with the bail money, he will continue to be transported between Cook County Jail and the courthouse, both of which have seen their fair share of star power in the last week or so, with Empire star Jussie Smollett being booked at the jail and heard at the courthouse as well.
The singer's next court date is set for March 22 at 10 a.m. local time.
Steve Greenberg told The Associated Press on Sunday that Kelly could be out as early as Monday, but he added that others have to act for him and the coordination is complicated because Kelly is behind bars.
Greenberg has said confidants were making arrangements to pay the $100,000 bail needed to free him as he awaits trial.
Prosecutors also described a witness who had access to videotapes showing Kelly having sex with a 14-year-old girl.
"Mr. Kelly has done absolutely nothing wrong", Greenberg said.
The "Surviving R. Kelly" docu-series revealed years of allegations of sexual misconduct against the singer as scores of people criticized the musician and hoped that the alleged victims would get justice.
Later on Monday, high-profile attorney Gloria Allred said in a news conference that she was now representing more than six women who allege the singer abused them.
Each of the 10 Class 2 felony counts carries a maximum of seven years in prison upon conviction but also could result in probation. He did not say if it was the same 14-year-old girl in the first video he turned over to the authorities.
According to reports, Michael Avenatti is also in the process of obtaining a third tape featuring a different girl. Together they detailed allegations that he held women against their will and ran a "sex cult". Kelly faces 10 counts of aggravated sexual abuse.
Prosecutors listed only one adult victim: a 24-year-old hairdresser who recounted a disturbing incident in 2003, during which Kelly exposed himself to her and tried to force her into oral sex.
"He's a rock star".
