"Julia is a total hippie," the bodyguard told Star. "She'll go days without showering."
She skips showering for a rather specific reason.
"She likes to save water — she's really green."
Not only is she energy aware, she also enjoys the feeling of not being showered.
"She likes the smell of her natural oils," the bodyguard said. "She also says that she can't wash her hair too often because it's dry."
Fortunately for Roberts, the bodyguard says she's met a kindred spirit in husband Danny Moder.
