The rumors that Tekashi 6ix9ine is working with the Feds have proven to be correct.

TMZ is reporting 6ix9ine pled guilty to nine charges last week.

Tekashi entered the plea on January 23 ... pleading guilty to all but one of 9 counts in the federal indictment. He copped to multiple counts of racketeering, conspiracy, firearms offenses and narcotics trafficking. The one count he did not plead guilty to is an April 3, 2018 robbery of rivals of the Nine Trey gang.

The narcotics trafficking charges involved dealing heroin, fentanyl, ecstasy, amphetamines, and marijuana.

No word on his sentence, but we assume it will be reduced for cooperation. He had been facing up to life.

Update: The 22-year old is facing a minimum of  47 years, unless the Feds ask the court for leniency. In his plea, he confessed to helping Tr3way members try to kill a rival, ordering a hit on Chief Keef, and selling a kilo of heroin, among other things. 

"I apologize to the Court, to anyone who was hurt, to my family, friends and fans for what I have done and who I have let down," 6ix9ine said at the hearing.
