R. Kelly recently stopped by the set of Transformers 3, while they were filming in the windy city of Chicago. Later on that evening Kellz, Tyrese and new Def Jam signee Leon Timbo , all got together for a little jam session where Kellz bust out in his very own R&B freestyle. Pure comedy! Kind of reminds you of what R-Kelly used to be in his prime. I really do miss them days. Welp, at least now we got Soulja Boy.

Props to NecoleBitchie.
