Naked Belly on 'Bethenny Getting Married?' (VIDEO)

This week on 'Bethenny Getting Married?' (Thurs., 10PM ET on BRAVO) Bethenny Frankel decides to celebrate her pregnant body and give her fiancé Jason Hoppy a real treat by doing a nude maternity photo shoot. Apparently it's the perfect gift for Jason who, says Bethenny, "as we all know, has a warped and twisted pregnancy fetish."

So wearing nothing but white undies, Bethenny lies across a bed and tries to get comfortable. It doesn't go great at first as the photographer starts taking photos before Bethenny's ready, and she's pretty tense in front of the cameras. But she gradually starts to loosen up and jokes that, "I feel like I'm in the doctor's office ... I feel like I'm in stirrups!"

Ever the trouper, Bethenny eventually gets into the groove and relaxes, even though "the last time I was naked with a camera was PETA and I was a whole lot different.".

And at the end of "the easiest photo shoot ever!" Bethenny says that she's really pleased with the results. After weeks of feeling tired and swollen she's got a set of pictures commemorating "this beautiful, beautiful time of my life."
