'Real Housewives' Kelly Bensimon gets naked for Playboy

kelly-bensimon-wire.jpg"Real Housewives of New York" costar Kelly Bensimon will bare it all in Playboy magazine.

Bensimon, 42, already the most controversial of the RHNY cast, will be on the cover and in a 6-page nude pictorial in the March issue, according to her rep.

Yes, that's right. We said nude. When did it go from semi-nude to nude? Maybe the photographer talked her into it.

The photog was Kelly's ex-husband -- famed French photographer Gilles Bensimon  -- also the father of her two daughters.
