Hugh Hefner's Halloween Bash

Happy Halloween Eve, everyone!

Last weekend Hugh Hefner held his annual Halloween Party at the Playboy Mansion.  Jeremy Piven came dressed as Fidel Castro (?), Chris Brown came dressed as a car that will run you over if-you-peep-my-phone-ho, Paris Hilton came dressed as slutty Fern Gully, and P-Diddy came dressed as Prince.

What are you going to be this year?  Better top cotton candy princess boobs over there.
