Kelly pleaded not guilty Friday, August 2 on multiple charges and was denied bail, says Newser.
USA Today reports that Kelly's lawyer Douglas Anton said he couldn't find the singer late Thursday.
The singer appeared in a New York federal court on a five-count indictment.
The indictment involved alleged sex crimes, including sexual exploitation of underage girls.
Two of Kelly's girlfriends attended "for moral support" and several supporters stood outside, TMZ reports.
