For a guy with a history of violence against women … a penchant for destruction … and an explosive temper … it’s no surprise Chris Brown decided to be a Taliban fighter for Halloween.

Brown — sporting a string of fake bullets across his chest — rolled over to Greystone Manor last night … to attend West Hollywood’s biggest Hollywood party … hosted by Rihanna.

Other famous in attendance … Flo Rida, Paris Hilton and U.S. Olympic team superstar Lindsey Vonn … but they all had better costumes.

Bonus Moronic Photo — Before he hit the clubs, Chris and his buddies grabbed some fake guns and posed for a group shot. He posed the pic with the caption, “Ain’t nobody F**king wit my clique!!!!”
