According to a new report from the New York Daily News, disgraced R&B singer R Kelly, who is awaiting sentencing after being found guilty of sex trafficking and federal racketeering, has befriended Frank James.

The accused Brooklyn subway shooter and Kelly have seemingly hit it off in jail at the Metropolitan Detention Center in Sunset Park, Brooklyn, New York. The former is currently awaiting trial in the April mass shooting on the subway. He faces charges of committing a terrorist attack or other violence against a mass transportation system and discharging a firearm during a violent crime after injuring 10 people.

He pleaded not guilty to his charges this week.

Sources within the detainment center told the Daily News that the pair “sit[s] together and eat[s] together” and get along well, with one calling the pair “buds” since they spend time together talking and going “out to rec.”

“Mr. Kelly is not in control of who he is housed with,” Jennifer Bonjean, Kelly’s lawyer, told the publication. “A friend is someone you voluntarily hang out with.”

In addition to his new liaison in prison, Kelly puts on impromptu performances, including a recent acapella performance of “I Believe I Can Fly” for a few fellow inmates.

The Chicago singer-songwriter faces a mandatory minimum of 10 years to life in prison and was found guilty of nine federal racketeering and sex trafficking counts after 50 witnesses testified during his Brooklyn trial last year.
