It seems that Sienna Miller's determination to make her sex scenes look realistic has landed her with a sore head.
The Factory Girl star recently admitted that she got into a painful problem while filming love scenes for her new movie 'Interview' with co-star Steve Buscemi.
The 25-year-old actress suffered head injuries after hitting her head on a kitchen sideboard.
"We were making out and I whacked my head really hard on the kitchen counter," The Sun quoted her, as saying.
Meanwhile Miller has admitted that she has a new man in her life, but insists that it's not P. Diddy.
Rumours of a romantic link-up between the British beauty and the rapper reached new heights after it was reported that Diddy's girlfriend, and mother of his three kids Kim Porter, had left the rapper and moved out of their apartment.
However, Miller insists that the reports of a romance are not true, and that she and Diddy are just 'good friends'.
