Hilary Swank says no to nude scene

Hilary Swank may have bared the truth about why her 13-year marriage failed in a recent issue of Vanity Fair.

In case you missed it, she told VF that her just-jettisoned hubby Chad Lowe had had a long "substance abuse problem."

But don't ask her to bare anything else.

Not even for a really, really good cause.
