50 Cent took to his Twitter account yesterday to call out Chief Keef for not showing up for his own video shoot. Fif and Wiz Khalifa were ready to go on the set of “Hate Being Sober” in Vegas but the star of the show was no where to be found. I’m pretty sure Keef is still on probation and not allowed to leave the state, but if that is the case why would he agree to a video shoot in Vegas? Fif pretty much warned the young rapper that be better tread lightly because he can and will get dropped if he keeps acting the way that he does. Part of me hopes that Keef doesn’t get it together so he will get dropped and we can say “Chief Keef, Who?” in a few months. See his tweets and some pics from the video shoot in the gallery.
