The crossover between the Chicago drill scene and the rest of the hip-hop world continues. We previously reported that Drake and producer Young Chop have a track together, and now it appears that one of Chop's frequent collaborators is branching out, too.

Chief Keef and 50 Cent hit the studio last night to record a "new joint," according to Fif. He admitted that the young rapper has "some heat" and Keef even took the above photo of 50.
