The British actress sparked speculation she is dating Getty again after the pair was spotted kissing during a romantic break in Italy last month (Jun09).
The couple was mired in controversy last year (08) after the Brothers & Sisters star reportedly cheated on his wife with Miller.
The Factory Girl star refuses to talk about the romance and lost her patience during a recent interview on Australian radio station Fox FM.
Miller launched a verbal attack on the radio reporter when she was asked about her beau.
During the conversation the star told the DJ to “p*ss off”, snapping, “You’ve called us scrags, b**ches, 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!”.
