Yes. That is Shelley Martin. She is a model, but hasn't produced any full nude work for quite some time.
Her website...

And another one, (but it's been "under construction" for the better part of a year or so)...

If you perform a search for "shelley" at LLP you'll find most, if not all, of the photos of her that were ever available, which is sadly not very many.
She is amazing. Hope we'll see more of her again in the near future.
