Sienna Miller vented her fury at a DJ after he asked a question about her on-off boyfriend.

The G.I. Joe actress was being questioned by a DJ on Australian radio station FOX FM, when she was asked whether she was still seeing Brothers and Sisters actor Balthazar Getty.

She snapped, "P**s off. You've called us scrags, b**ches, knocked up.

"We're not here to talk about him. But, yes, I know him and everything's good, thank you. What a scoop! Congratulations! You're really, really clever."

Miller was in the headlines last year after Getty reportedly left his wife for the British actress.
