Sydney, Australia (BANG) - Sienna Miller launched into a foul-mouthed rant after being quizzed about her love life. The "G.I. Joe: The Rise of Cobra" actress flew into a rage and told a radio host to "p**s off" when asked if she is still dating on/off lover Balthazar Getty.

During a phone interview with Australian radio station Fox FM, Sienna fumed: "You've called us scrags, b****es, knocked-up. We are not here to talk about him [Getty]. But, yes, I know him and everything is good, thank you."

"What a scoop! Congratulations! You are really, really clever!"

Radio host Adam Richard tried to apologize for upsetting the 27-year-old blonde star by saying: "I didn't mean to step on your toes."

However, Sienna refused to calm down and snapped back: "You're going there."

Last month, it was claimed Sienna had reunited with married actor Balthazar. The "Brothers and Sisters" actor reportedly whisked the British star off to Italy for a romantic break.

Balthazar, 34, and Sienna sparked outrage when they were first linked last July.

His wife Rosetta Millington - who has four children with the billionaire actor - subsequently split from the star, but they are yet to divorce.
