Prosecutors on Saturday laid out their case against Kelly - detailing abuse allegations that span 12 years and involve four separate victims. "There are a total of four alleged victims".
Attorney Michael Avenatti, who is thought to be working with several individuals making accusations about Kelly, has claimed to have an unreleased video of the singer engaging in sexual acts with an underage girl.
Greenberg has told the court that Kelly has no money to make bail, and that his recent history of unpaid rent and unpaid child support shows this.
His lawyer Steve Greenberg had said Saturday that Kelly was not as rich as his fame would suggest.
Lizzette Martinez said she was a teenager when she first met Kelly. An infamous tape that allegedly showed Kelly urinating on a young girl formed the basis of his 2008 child pornography trial; Kelly denied it was him on the tape, and was acquitted after the girl said to be on screen refused to testify.
"Over the weekend, we have encountered a number of additional witnesses who we have interviewed, who we are in the process of preparing to meet with prosecutors", Avenatti told CNN Monday.
"The conduct in the tape can be described as nothing short of outrageous and illegal", the lawyer told reporters. She said the only person lying is Kelly and that he has done so "for more than 20 years".
Kelly's DNA was found in semen on one of the accuser's shirts, and semen found on a shirt worn by another was submitted for DNA testing, Cook County State's Attorney Kim Foxx said.
Avenatti, 48, who is now representing six clients - two alleged victims, two parents and two "whistleblowers" - in the investigation against Kelly shared screenshots from the alleged sex tape on his Twitter account and addressed them further during a press conference held on Friday. Kelly is accused of having penetrative and oral sex with the alleged victim multiple times between May 1, 2009 and January 31, 2010, and physically assaulting her by choking and slapping her, and at times spitting on her, throughout the relationship.
Kelly has hit songs like "I Believe I Can Fly", "Ignition (Remix)" and more. The charges carry three to seven years of prison per count.
