Rapper Jim Jones was exposed by incarcerated gang banger Tekashi69 as a card-carrying member of the Nine Trey Bloods street gang.

Tekashi69, also known as 6ix9ine, real name Daniel Hernandez, sang like a canary in heat on the witness stand during his first day of questioning on Thursday.

The 23-year-old rapper testified as a government witness against several members of the Bloods in his ongoing racketeering case.

On Thursday, Teskashi confirmed that Jones was in the gang’s back pocket. Later, under cross-examination, Tekashi also confirmed Bronx rapper Cardi B is a member of the notorious Bloods street gang.

It is a well-known fact that Cardi reps the Bloods. She often brags about her gang affiliation in rap lyrics.

“You joined the Bloods to advance your music year?” attorney Alex Huot asked Tekashi.

“Yes,” Tekashi replied.

“You knew Cardi B was a Blood?” Huot asked.

“Correct,” Tekashi said.

“You knew Cardi B made music videos with Bloods in the background?” the attorney asked.

“Correct. I didn’t pay attention,” Tekashi said.

Jones, who is a high-ranking member of the Nine Trey Bloods, was caught on a wiretapped phone call telling a godfather of the Nine Trey Bloods he’d “best get to violating” Tekashi 6ix9ine for splitting from the gang.

In a taped phone call dated Nov. 17, Jones and Jamel “Mel Murda” Jones (no relation) discussed Tekashi’s comments denouncing the Bloods during a radio interview on Power 105. The men agreed that Tekashi had humiliated high-ranking Bloods member Kifano “Shotti” Jordan, who was the Brooklyn rapper’s manager.

Mel Murda is heard telling Jones that Tekashi should be “super violated. Super duper.”

Jim Jones responded, “Tell that n — – a he’s not a gang member no more. He kicked out the whip. He was never a gang member … He was always a money ploy for the gang members.”

He added, “They gonna have to violate shorty ’cause shorty on some bull***t. He better get to get to violating.”

“Violated” is street slang for murdering or torturing a gang rival.

Tekashi and Jordan were both arrested along with other gang members in a federal racketeering sting operation last year.

Tekashi is being held without bond in a federal detention facility awaiting trial.
