Was Sienna & Hayden's Sex Scene the Real Deal?

Sienna Miller and Hayden Christensen briefly dated while filming "Factory Girl" last year. Sources on the set now claim that the sex scene in the movie wasn't simulated. The pair briefly hooked up while Sienna was on a break from Jude Law. She decided she didn't want anything serious from Hayden and broke his heart. Months later during reshoots of the film in Toronto, Sienna couldn't help her vagina and decided to have it another go. It was during these reshoots that the two became instant porn stars.

Sienna's rep denies the rumor, "She's just a really good actress."

Um...no she's not. She's also a huge slut and the two together equals sex on film! I hope the uncut sex scene featuring a jizz-on-titties is on the DVD!
