The Anthony Pellicano trial, an “inside-baseball” clambake of Hollywood privilege, blackmail and other shenanigans, saw a recognizable face take center stage when Chris Rock appeared Friday for around 20 minutes, to testify about his hiring of the “dark-side” private investigator to investigate (read: discredit) a shake-down paternity claim by sketchy Hungarian model Monika Szibrita. Mark Lacter recaps the nasty bid-ness on LA Observed. Too bad Tom Cruise and some of the other Hollywood heavyweights who used this guy — retaining plausible deniability by claiming they were relying on attorneys’ recommendations — won’t be called to testify.
