Okay, I researched the hell outta this and came up with some new info & pics. The original pic came from JST Photography. I found some more pics of her, but still no name. Hopefully, someone else can take the info I dug up and find more.
Below is the link where I found the extra pics. There are a few more pics, but I left those out as they did not show her face.
I read a post (from last year) on DeviantArt from the photographer that he was supposed to do a pregnancy shoot with her, but they aren't on his DA page, so I assume he either didn't do it, or he didn't post the pics.
In case anyone is still interested in this, apparently the name of the model is "Nadia." She has a profile at Model Mayhem here: http://www.modelmayhem.com/731901
