Jessica Biel is so convincing as a stripper in new movie Powder Blue, her dance trainer has tipped her for a career in the adult industry if the Hollywood roles ever dry up. Justin Timberlake’s girlfriend is sure to titillate male fans with her topless role as exotic dancer Rose Johnny in the upcoming drama, which also stars Forest Whitaker, Ray Liotta, Lisa Kudrow and Patrick Swayze as a seedy club boss. Biel underwent a vigorous training schedule to prepare for the part and her teacher, Cati Jean, is so impressed, she’s confident the actress would make a decent living if she decided to take her dancing one step further. Jean says, “Jessica is so good and so focused. She has the beauty element, she has the body, she has all the package that you want in a professional dancer. She could be a professional dancer if she wanted to. She is strong, she is flexible.”
