Real Housewives Star Goes Nude In Playboy

Which Real Housewife is getting extra comfortable with the cameras?

That would be former model Kelly Bensimon, who bares all for the March issue of Playboy mag.

Bensimon's ex-husband, fashion photographer Gilles Bensimon, reportedly snapped her for the cover and six-page spread inside.

Is it purely coincidence that Bensimon's sworn onscreen rival, Bethenny Frankel, went nude in a PETA ad and billboard last month? And now she's engaged and pregnant. What's a Bensimon to do to get some attention around here?

The third season of The Real Housewives of NYC premieres on Bravo March 4.
