Actress Jessica Biel says she is concerned about what her family will think about the nude scenes in her new movie Powder Blue.

Biel told Glamour: "I definitely worry about how my family would react. You can't help thinking about your dad or your brother seeing something."

The star, who is the girlfriend of Justin Timberlake, will play a stripper in the film.

Talking about the movie, she commented: "I don't have to be fully naked for the movie. I haven't decided exactly about the nudity. It's a tough one. I'm considering it but it's a very scary thing to do.

"It definitely feels vulnerable to be naked in front of anybody, let alone a film crew."

She added: "And it's scary because of the internet - you don't know where it's going to end up. It's a moment that could be exploited. I don't worry much about being sent roles that require me to be naked because this is such a beautiful script and it's not gratuitous."
