So you know that Sienna Miller sex scene from Factory Girl that was posted here a little while back (but then had to be taken down because of studio pressure)? Well, some people say that sex scene was actually the real thing. According to The New York Daily News, Sienna Miller and Hayden Christensen were so hot for each other at the time of filming, that they went a bit further than just play acting they sex scenes. Further as in all the way.

"It's not simulated," an insider tells us. "They're really doing it."

It was during the film's Louisiana shoot that Miller ran into another squall in her stormy romance with Jude Law - and turned for comfort to Christensen, the "Star Wars" heartthrob.

"They spent about a month hanging out," says one pal of Christensen. "But then she decided she didn't want a relationship. Hayden was devastated. He really fell for her."

Added a friend of Miller, "Sienna wanted to try to make another go of it with Jude. But, again, it didn't work out. At the end of last summer, she and Hayden ended up in Toronto for more shooting. They hadn't talked in six months. But it turned out to be a great reunion."

At the movie's premiere on Monday, director George Hickenlooper would tell us only: "Sienna and Hayden grew close during the filming. It was an emotional experience for all of us." As for the sex, he said, "We tried to portray it tastefully."

And was congress actually in session during the shooting?

"I can't comment," Hickenlooper answered. "You'll have to ask Sienna about it."

Miller left the Chelsea Hotel after-party before we could ask about the love scene - and where she now stands with Christensen, who wasn't at the premiere. Yesterday, Miller's publicist said the sex wasn't bona fide: "She's just a really good actress."

Well, I saw that scene, and I can definitely say you can't see for sure, but it is hot. There have always been rumours about sex scenes in movies being more than just pretend, but if you ask me, this rumour would have come out earlier if it was really true. The fact that it's coming out the week of the premiere really makes me think it's just another PR gimmick to drum up publicity.

Of course, we are talking about Sienna Miller, so anything is possible.

Now that the scene in question is actually news-worthy, you guys can see it.
