Diddy has landed a pretty major promotion for himself and his music by guest appearing in an upcoming episode of the CBS show “Hawaii Five-O.” The show will also include a line up of Diddy and Dirty Money’s recent singles. In the show, Diddy will undergo weapons instruction and training with a Navy SEAL to play New York City Detective Reggie Williams, a lawman “who hunts the streets of Honolulu for the men responsible for a crime against his family,” CBS said in a statement Wednesday.
