One of the most-anticipated witnesses in the trial so far, rapper Kid Cudi, took the stand and called Diddy a "Marvel Supervillain."  He also accused the mogul of trashing his house and blowing up his car.  But that's not the testimony that floored Amy and T. J. the most.  Wait until you hear Diddy's "guest profile" at one LA hotel that includes an instruction for staff to spray air freshener in the hallway outside his room.
