The singer, whose full name is Robert Kelly, turned himself in on sexual abuse charges on Friday. In the days that followed, he had difficulty making bail. It was not immediately clear where the money came from on Monday.
Kelly's lawyer had said the singer's finances are "a mess."
"This is someone who should be wealthy at this stage in his career and through mismanagement and through hangers on and bad contracts and bad deals and bad leases – like he had in his studio – he really doesn’t have any money," attorney Steve Greenberg told reporters Monday.
The "I Believe I Can Fly" singer was once said to be worth $150 million.
Kelly has pleaded not guilty to the abuse charges and denies all allegations of wrongdoing.
Inside Edition spoke to Asante McGee, a woman who has accused Kelly of abuse and who was featured in the Lifetime docu-series "Surviving R, Kelly." She had hoped that the claims he could not afford bail were "not a tactic from his legal team to pretend like he doesn’t have the money to post bond in order to try and get a lower bond."
Kelly is in Cook County Jail, the largest jail in the nation that can hold over 6,000 inmates.
