Comedian Katt Williams is on a tear with police! Arrested after a bar fight, and slapping the holy hell out of a Target employee ... it's the latest in a string of bizarre incidents! Is Katt losing his mind -- or just falsely accused ... multiple times? Plus, 86-year-old Hugh Hefner and 26-year-old Crystal Harris engaged ... again ... after she dumped him the first time. Is Hef stupid -- or king pimp for taking back the ex-Playmate? Also, Lenny Kravitz is playing Marvin Gaye in a new movie ... but the Motown legend's son, Marvin Gaye III, joined us to rip the project -- and to explain why he's trying to shut it down!
