Hollywood film industry and the California porn industry seem to be walking so closely hand in hand that they are basically the same thing! Movie actors are making porn videos (ie: Colin Farrell and the list goes on) and major porn stars have the success, money, and fame of Hollywood movie stars (ie: Jenna Jameson). Movies such as “‘Short Bus” by Director John Cameron Mitchell are so sex-centered that they toy & tamper with the boundaries of porn. See how Sienna Miller and Hayden Christensen get in on the action after the jump…

Real love, or, simply lust, truly came to life on the set of “Factory Girl”. Sienna Miller, who plays the 60’s socialite Edie Sedgwick (the muse of Andy Warhol), became very close with her Star Wars co-star, Hayden Christensen, during the film. She had just broken up with Jude Law and Hayden was there to comfort her. They spent lots of time together and were secretly, very intimate. Sienna called off the love fest while the film was on hiatus – claiming that she wanted to make it work with ex-boo Jude Law.

When things didn’t work out there Sienna probably started frollicing around town with the likes of Diddy and friends. When she came back to set, it was time for her and Hayden to shoot the big love scene and according to an insider on the film set – both mutually agreed to “couple” up live and in the flesh during the romp session. Once the cameras started to go, Director George Hickenlooper said that it turned into “an emotional experience for all of us.”

Damn! That’s some good sex when people who aren’t even participating are getting emotional. Or maybe it just was one huge organized orgy?! The Director didn’t say whether the two stars did or did not actually have sex but you can presume so. Miller’s representatives claim that there was no actual sex between the two, and that Sienna is just a really good actress.

I smell a heaping pile of s#!@ … Bring on the porn and lets all go see “Factory Girl”!
