THIRTEEN star Evan Rachel Wood was so nervous about doing a sexy dance for her new movie Pretty Persuasion, she got the film crew to perform it for her first.

The 18-year-old actress had to perform the routine twice in the film, and admits she needed a little encouragement to get started.

She says, "I'm not really taking my clothes off or anything, but I did have to do this kind of like sexy dance. I was very uncomfortable and didn't really know what I was gonna do, but the director had a rule that if you're ever uncomfortable doing something the entire crew had to do it first.

"So I got like five grips to come over and do a little sexy dance with their walkie-talkies hanging off of their belts and stuff. It was awesome and then I felt totally fine."
