Hilary Swank has sparked a storm of controversy in the U.S. by confessing she's often nude in front of her boyfriend's six-year-old son in a new magazine article.

The actress tells the new Marie Claire that she never wears anything to bed and that means her lover's kid often sees her naked, prompting top psychologists to urge the Oscar winner to cover up.

In the article, Swank says, "My boyfriend's son is six years old, and you wonder at what age you should stop walking around nude. Every morning he comes into the bedroom, and you're just nude. But he doesn't look twice; he doesn't think about it yet."

Qualifying her Marie Claire remarks during a TV interview on Monday morning, the Boys Don't Cry star added, "I think every family's different and you have to know what's right for you and your family."

But top psychologists don't agree - Dr. Jeff Cardere says, "Hilary, you're not this child's mum. What if things don't work out with your present boyfriend...? Who knows what might happen in the future; what his psycho-sexual adjustment may be. It's not a good thing."
