R. Kelly, the singer, and convicted sexual predator, will stand before a judge in a Brooklyn federal court today.

For sentence for racketeering involved a dozen distinct criminal actions, including sex with young females.

The former R&B singer, whose actual name is Robert Kelly, might be imprisoned for the rest of his life.

Due to the seriousness of his acts, federal prosecutors believe he should be punished with "in excess of 25 years."

R.Kelly, 55, was found guilty on nine other criminal charges in September during his sex-trafficking trial, 

including managing a criminal business that recruited women and minors for sex, which prosecutors described as "planned" and "methodical."

Nearly four dozen witnesses testified for the prosecution during his trial, stating that he preyed on children and women for sexual enjoyment.

He was also convicted in a bribery conspiracy involving a public official to obtain a phony ID for the late singer Aaliyah in order for the two to marry when she was 15 and he was 27.

Prosecutors claimed in a sentencing letter in the court that Kelly believed Aaliyah was pregnant at the time.

Aaliyah's debut album, "Age Ain't Nothing But a Number," was produced by Kelly. She was 22 years old when she died in an aircraft crash in 2001.
