CHICAGO (AP) R&B singer R. Kelly pleaded not guilty to 11 additional sex-related charges on Thursday, including four counts that carry a maximum prison term of 30 years in prison.

Prosecutors did not ask the judge to raise the bond amount for Kelly during the brief hearing in Cook County court.

Kelly stood with his hands folded in front of him and listened to Judge Lawrence Flood describe the charges to him. When Flood asked if he understood, Kelly, responded, Yes, sir. The Grammy award-winning singer, who has denied any wrongdoing, left without speaking to reporters. A status hearing was scheduled for June 26.

Among the 11 new counts are four counts of aggravated criminal sexual assault, which carries a sentence of up to 30 years in prison. That is more than four times as long as the maximum term for each of the 10 counts Kelly was originally charged with in February.

Kellys defense attorney, Steve Greenberg, said after the hearing that he couldnt speculate as to why prosecutors brought the new charges, which pertain to one of the four women he was charged in February with sexually abusing years ago, three of whom were minors when the alleged abuse occurred.

Its the same case. Its just that theyve just changed what theyve charged him with, Greenberg said. Its the same facts ... the same bond, the same evidence. We expect the same result.

Asked how Kelly is coping, Greenberg said, Its tough. Everything is against him.

Kellys spokesman, Darryll Johnson, told reporters that Kelly is upbeat.

Initially, he was a little depressed, Johnson said. But I mean, with anything, if someone accuses you of something, youll be depressed. He knows the truth.

According to the new indictment, the first eight counts are from encounters that allegedly occurred between Jan. 1 and Jan. 31, 2010. Three others pertain to alleged encounters between May 1, 2009, and Jan. 31, 2010.

Among other things, prosecutors allege that Kelly used force or threatened to do so to pressure the accuser into sex or to perform oral sex on him. Since she was underage at the time, the statute of limitations for bringing charges was extended to 20 years from her 18th birthday, they wrote.

A woman has come forward to say publicly that 11 new felony counts stem from allegations she made about the R&B singer.

Jerhonda Pace wrote on her Facebook page that shes the accuser identified as J.P. in court documents. Anticipating an angry reaction by Kellys fans, Pace one of four women Kelly is charged with sexually abusing wrote that no matter how wrong you think I am, the law is on my side, a MINOR at the time.

The Associated Press doesnt usually name alleged victims of sexual assault, but Pace has gone public with her allegations.
