What's with actresses and their sex scenes? Between Kate Bosworth getting drunk and Sarah Michelle Gellar almost falling asleep, they need to lock it up! SMG is in a new flick called Southland Tales in which she plays a porn star. She says she had trouble staying awake for her raunchy sex scene because she had just eaten a huge Thanksgiving dinner. Not the best idea right before you shoot a nude scene, but whatever floats your boat.

She said, "I filmed a love scene on Thanksgiving and I had eaten all this turkey and mashed potatoes. I was like, 'I seriously have to film a sex scene right now?' I was so tired from all the tryptophan - an amino acid in turkey that makes you sleepy - that I just wanted to sleep!"
