The blonde beauty is currently in Australia promoting the new sci-fi thriller GI Joe: The Rise Of Cobra, but she lost her cool in a telephone interview with Aussie station Fox FM.

Sienna began datng Getty last summer, just after he and his estranged wife had just had their fourth child.
He later announced he had split from his wife, although neither has yet filed for divorce.

Sienna told jock Adam Richard to “piss off” and called him a “douche bag” after he asked whether she was still seeing the star.

“You’ve called us scrags, bitches, knocked-up. We are not here to talk about him (Getty). But, yes, I know him and everything’s good, thank you. What a scoop! Congratulations! You’re really, really clever!” she snapped.

Richard quickly apologized for upset the actress: “I didn’t mean to step on your toes.”

But Sienna sharply fired back: “You’re going there.”
