R. Kelly was denied bail by a federal appeals court in New York City on Tuesday.

The R&B star, 53, awaits multiple trials for sex crimes and is currently behind bars in Chicago.

His lawyer cited a recent physical attack by a fellow inmate as a reason why the star should have been granted release on bail.

The singer has denied all allegations against him.

Additionally, he's been deemed a danger and a flight risk, and the appeals court said prosecutors proved that "no condition or combination of conditions could assure against those risks" and that Kelly had no "compelling reason" for a temporary release.

R. KELLY'S LAWYERS ARE SEEKING TO QUESTION GANG MEMBER IN PRISON ATTACK

Mike Leonard, an attorney for the Grammy winner, called the ruling "very disappointing and somewhat surprising" because it appeared that judges understood that Kelly could not prepare for trial while incarcerated.

In a Chicago federal court filing Friday, Leonard stated that Kelly suffered unspecified injuries from another inmate in late August.

He claimed the attack was proof that Kelly could not be protected by authorities, hence the request for bail.

"The so-called maxim of the presumption of innocence appears to be a misnomer" for Kelly, said Thomas Farinella, another one of the singer's attorneys. "We will continue to vigorously fight for Mr. Kelly’s vindication."
