Sienna Miller: Sex on Factory Girl Set

So, the big rumor around tinseltown is that Sienna Miller and Hayden Christensen bumped uglies on the set of their latest movie Factory Girl.  I’m not sure if I would put anything past Sienna, but I’m just not so sure about this one. Apparently the news is that there was actually penetration during the sex scene for the movie. 

Well, you might as well go ahead & enjoy it, right?  The rumors were fueled by Factory Girl’s director George Hickenlooper who when asked about the indecent set activity stated, “I can’t comment. You’ll have to ask Sienna about it.”
