Fake Real Sex Vs. Real Sex

Yesterday, the Daily News reported a rumor that Sienna Miller (aka Leotard In Public) and Hayden Christensen (guy who possibly, at one time, dated Leotard In Public) had actual sex, as opposed to simulated actual sex, while filming a love scene for Factory Girl. Today, to counter that story, The NY Post reported a rumor that Sienna Miller is a really good actress.
Both rumors are probably false. But just to be sure, I've compared video of the allegedly real sex scene from Factory Girl, to a video whose authenticity cannot be denied: A commercial for The Punany Poets, a group featured on the most horrific episode ever of HBO's Real Sex.
