Rachel Bilson

Sexy Hollywood star Rachel Bilson was so scared filming a sex scene with actor Hayden Christensen that she drank shots of alcohol to make herself calm. The actress was a wreck before stripping off for the new movie 'Jumper' and is insisting that it goes against nature to simulate sex on a film set.The 26-year-old says, "I remember Hayden and I were both like, ‘Let’s drink a shot or something to calm our nerves.’ "Because it’s just so awkward I mean, this was a very mild scene compared to the one in The Last Kiss, but it was still nerve-wracking."I don’t think that’s ever going to be a comfortable thing for me. It’s just something that goes against nature."
