Lil Durk may find himself in hot water over a controversial lyric on his latest single.

On his most recent release "Dis Ain't What U Want," the Glory Boyz Entertainment affiliate raps that, "A nigga claim 3Hunna/Add a K, you done." The line is an apparent reference to slain 16-year-old Chicago rapper Lil JoJo, who released a diss towards Durk titled "3HunnaK."

Prior to his death, JoJo was embroiled in a feud with Durk, as well as his Drill associates Chief Keef and Lil Reese. The origins of the feud are unknown.

Chief Keef became the target of a police investigation following JoJo's death last year after he Tweeted, “Its Sad Cuz Dat Ni—a Jojo Wanted To Be Just Like Us #LMAO."

Check out the full song below. The lyric in question can be heard at the 2:27 mark.
