Sean “Diddy” Combs is a busy man behind bars.

The disgraced rapper, 56, is enrolled in an intensive drug treatment program and working in the chapel at the Fort Dix Federal Correctional Institution in New Jersey, according to CBS News.

Court documents obtained by the outlet revealed that Combs has been assigned to the Residential Drug Abuse Treatment Program unit, which is the Federal Bureau of Prisons’ most intensive drug treatment program.

Inmates allegedly need to qualify for the program and rarely get placed in an RDAP at the start of their sentence.

Enrolling in the Bureau of Prisons’ drug treatment program can reduce a prison sentence by up to one year, CBS News reported.

Combs’ publicist, Juda Engelmayer, claimed the Bad Boy Records founder “has taken his rehabilitation process seriously” since he first reported to prison.

“He is fully engaged in his work, focused on growth, and committed to positive change,” Engelmayer told CBS News.

Combs’ lawyers previously requested he serve his 50-month prison sentence at New Jersey’s FCI Fort Dix because of the low-security prison’s drug treatment and rehabilitation program.

He moved to the facility in the Garden State from the Metropolitan Detention Center in Brooklyn last month.

Combs is also working as a chaplain’s assistant, considered one of the more desirable assignments at the Fort Dix prison, according to CBS News.

A former prison commissioner told the outlet that inmates typically maintain the chaplain’s religious library, clean their office and help with some recordkeeping. 

The chaplain’s assistant also reportedly gets to work in a private office, typically with air conditioning, and can have some of the food that the chaplains bring in for religious services.

“He works in the chapel library, where he describes the environment as warm, respectful, and rewarding,” Engelmayer told CBS News.

But Combs hasn’t been on his best behavior during his time behind bars.

CBS News also reported that he allegedly got in trouble for participating in a prohibited three-way phone call on Nov. 3, just four days after he was transferred to the facility.

Combs reportedly called an unnamed woman to discuss arranging visitors for the weekend and suggested they bring “200 singles” — despite prison regulations banning visitors from bringing in currency other than coins for the vending machines.

The music mogul also allegedly said he needed to speak with someone described as “the digital person” regarding blogs, and when the woman asked if he should add that person to the call, Combs replied, “Yes.”

Combs later claimed to officials that he was speaking to his attorney and she added the head of legal communications to the call so they could work on a statement for The New York Times. Combs denied he was talking about blogs and insisted he did not receive the prison admission and orientation handbook that outline the prison’s phone call regulations.

According to CBS News, prison officials recommended that Combs lose 90 days of phone privileges and 90 days of commissary privileges for the rule-breaking, though it’s unclear if the penalties have gone into place.

“This is a serious offense that shows a disregard for the rules,” a source close to the investigation told the outlet.

But Combs’ publicist told The Post, “He participated in a routine and appropriate attorney-client privileged call that was initiated by his attorney.”

The rep added to CBS News, “It was a procedural call initiated by one of his attorneys and was protected under attorney client privilege. There was nothing improper.”

After Combs entered Fort Dix, TMZ reported that he was caught drinking “homemade alcohol,” which the rapper’s rep denied.

“His only focus is becoming the best version of himself and returning to his family,” the rep tweeted on Combs’ X account.

In July, Combs was convicted on two counts related to prostitution but was found not guilty on two counts of sex trafficking by force, fraud or coercion, and on racketeering conspiracy, following his bombshell NYC trial.

He was sentenced to four years in prison on Oct. 3, with his scheduled release date being May 8, 2028.
