Singer R. Kelly could face more than two decades in prison when he is sentenced later on Wednesday over running a racket to abuse women and children.

The R&B singer, 55, was convicted last September in a US federal court in New York on charges of racketeering and eight counts of sex trafficking.

Prosecutors have argued that Kelly, who became a household name with songs such as I Believe I Can Fly, should be jailed for more than 25 years.

They say he demonstrated a “callous disregard” for his victims and showed no remorse.

Lawyers for Kelly said he deserves no more than 10 years, the mandatory minimum, arguing his history as an abused child may have led to his adult “hypersexuality” and that he no longer poses a risk.

US District Judge Ann Donnelly is scheduled to sentence Kelly at a hearing starting on Wednesday afternoon.

A jury convicted the singer after hearing how he trafficked women across different US states over two decades, assisted by his entourage of staff.

Victims testified that Kelly subjected them to threats and punishments if they disobeyed his orders.

The court also heard how Kelly had illegally obtained paperwork to marry singer Aaliyah when she was 15 in 1994, with the marriage certificate falsely listing her age as 18.

He was 27 at the time. The marriage was later annulled.

Aaliyah worked with Kelly, who wrote and produced her 1994 debut album, “Age Ain’t Nothing But A Number,” and died in a plane crash in 2001 at the age of 22.

The singer has yet to face federal child pornography and obstruction of justice charges in Chicago, where a trial is scheduled to begin on August 15.

He also faces state charges in Illinois and Minnesota.
