LOS ANGELES — She may have what most consider a figure fresh from “7th Heaven,” but Jessica Biel is still bothered about flashing her flesh for a film.

According to insiders on the set of her latest movie, “Powder Blue,” the Hollywood hottie is dreading getting down and dirty in the presence of a camera crew, particularly due to fears that her bare body could be exploited on the Internet.

But perhaps Jess has decided that a new ‘do will help her go a little more incognito — she’s ditched her golden locks for darker strands.

Her beau, Justin Timberlake, doesn’t mind the brunette Biel, as the pop prince was recently spotted in Santa Monica buying a “commitment” ring for his glowing girlfriend.

But according to an insider from Life & Style, JT doesn’t want to walk down the aisle just yet, he simply wants to symbolize his love and affection.
