When we last checked in on the 50 Cent and Teairri Mari's beef, Mari was being forced to pay Fif 30K because he was awarded 30K in the revenge porn lawsuit she filed against him after he posted very, very explicit images of her on his Instagram page.

Instead of paying him, Mari dropped the 50 Cent diss track "I Ain't Got It" and claimed that she had just "ended" Fif's career.

50, whose career happened to take a very Instagram-based turn several years ago, has responded to that by jumping on IG with some trademark trolling.
