Miller and Christensen sex scene sparks rumours

Sienna Miller’s sex scene with Hayden Christensen in her new movie is so steamy it has prompted speculation it might be more than acting.

Those who have seen Factory Girl say the sizzling clinch is even saucier – and more revealing – than the famous are-they-or-aren’t-they love scene between Julie Christie and Donald Sutherland in 1973’s Don’t Look Now.
