A source recently told New York Daily News that the sex scene in the movie is 100% for real.

Of course Sienna's publicist denies the reports. "When you do a love scene there is a minimum of five people in the room. There's no real sex and the scene proves she knows how to give a good performance," she told TMZ.com.

Oh, I bet it was. Heh.
When asked if the sex scene was real he stated, "I can't comment. You'll have to ask Sienna about it."
