When Lil Durk recently previewed a new "Chiraq" freestyle in which he took shots at Tyga, the reasoning behind the attack wasn't too clear.

The drill rapper explained in a subsequent interview that Tyga had requested that Durk change a line about Blacc Chyna in one of his raps. Durk, who was apparently paying tribute to Tyga's girl, rather than dissing her, agreed to change it in exchange for a collaboration with T-raww.

The Hotel California rapper was apparently cool to do a song with Durk, but later dodged the rapper's texts when it came time to work together. At that point, Durk decided to diss him on record.

That "Chi-Raq" remix just hit the net, and Tyga has already fired back with a clip from his own freestyle over the instrumental.

In the Instragram vid we hear T-raww say "Niggas think that they MCs/ Can't get touched/ Well it's hammer time/ Who the fuck is Lil Durk?"

Durk has already seemingly responded on Twitter with a quote from his freestyle. View both the video and tweet below.

[UPDATE: Full Track Released]
