CSI Star Cameos

A slew of special guest stars have appeared through the years on CSI: Crime Scene Investigation, including Kevin Federline (as in Britney's ex) on a Season 7 episode titled (what else?) "Fannysmackin'." And even Ray Donovan's Liev Schreiber guested as Gil Grissom's (William Petersen) temporary replacement on Season 7.

Other one-offs have included Faye Dunaway (Bonnie and Clyde), Roger Daltrey of The Who (whose song "Who Are You?" opens CSI) and Danny Bonaduce (The Partridge Family).
