Rose to Arnold: You Screwed Up Kaleefornia!!!
The smack talk has officially begun between -- the chick with the machine gun leg bashing the hell out of The Terminator.
From the minute Rose McGowan left a masquerade at Guys nightclub in Hollywood last night, the "Grindhouse" star unleashed an intense Anti-Schwarzenegger tirade -- slamming the Guv for "getting nothing done" for the state of California.
It's the sexiest political trash talk we've ever seen.
